SUMMARY:S&A Colloquium: Rowina Nathan (Monash University)
DESCRIPTION:Understanding the gravitational wave background: pulsar timing arrays and skymapping\n\nAbstract:In June 2023\, members of the International Pulsar Timing Array (IPTA) released coordinated evidence for the gravitational wave background. In this seminar\, I will explain how pulsar timing arrays measure the gravitational wave background and discuss the latest results from various arrays.The MeerKAT radio telescope\, one of the most sensitive in the world\, has detected similar evidence after just 4.5 years of data collection through the MeerKAT Pulsar Timing Array. Thanks to its exceptional sensitivity and the new methods we have developed\, we have produced the most accurate maps of the gravitational-wave background to date. I will discuss our advances in skymapping methods and results. Mapping is crucial for understanding the origin of this background\, as an anisotropic background suggests supermassive black-hole binaries as the source. Notably\, we identify a hotspot in the 7 nHz map with a p-value of 0.015. \n\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Piyush Mehta (CISER / West Virginia University)
DESCRIPTION:Next-Gen Tools and Techniques for Space Situational Awareness and Space Traffic Management\n\nAbstract:Space debris remains a persistent threat to assets and humans in space. The proliferation of low Earth orbit (LEO) with replenishable small satellite constellations driven by commercial interests has further stressed Space Situational Awareness (SSA) and put focus onSpace Traffic Management (STM). While the trackable debris catalog has grown significantly over the last decade\, lethal non-trackable (LNT) debris smaller than the order of centimeters in size remains a challenge as they fall below the detection and tracking capability of most ground-based sensors. In addition to catalog maintenance under SSA\, STM has put focus on enhanced and concerted space operations that includes conjunction assessment and collision avoidance. \n\nThe US Space Policy Directive-3\, National STM Policy has emphasized the necessity “to make significant contributions to establish a quality threshold for actionable collision avoidance warning to minimize false alarms”. Accurate calculation of Probability of Collision (PoC) for confident decision-making requires realistic covariance information since maneuvers are expensive (personnel cost\, science data or commercial service outage\, fuel costs). This talk will cover the work developing tools and algorithms targeted at addressing the challenge of LNT debris and enhancing LEO operations\, critical for a safe and sustainable space economy and environment. \n\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Kshitij Bane (NCRA\, Pune)
DESCRIPTION:Under the SPOTLIGHT: Hunting Fast Transients in Real Time with the uGMRT\n\nAbstract:The detection of Fast Radio Bursts (FRBs) has grown exponentially in recent years\, but real-time localisation with high precision remains one of the key challenges in the field. SPOTLIGHT is a next-generation system developed at the upgraded Giant Metrewave Radio Telescope (uGMRT) to tackle this challenge. Operating commensally with regular uGMRT observations\, SPOTLIGHT employs a high-performance\, multi-node GPU cluster to handle petabyte-scale data processing in real time\, steering 2000 post-correlation beams at sub-millisecond resolution. \n\nPowered by an AI-driven transient detection pipeline\, SPOTLIGHT not only captures FRBs in real time but also triggers arcsecond-level imaging and raw voltage dumps for high-resolution studies across the 300–1460 MHz band. With its exceptional sensitivity\, SPOTLIGHT is expected to detect and localise hundreds of FRBs\, offering exciting prospects for understanding their origins. \n\nIn this talk\, I will present an overview of the SPOTLIGHT project\, its architecture\, performance\, recent tests\, and the scientific opportunities it unlocks. \n\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Sanne Bloot (ASTRON / Kapteyn Astronomical Institute)
DESCRIPTION:From exoplanets to long-period transients: Coherent radio emission from binary systems\n\nAbstract\n\nMany binary systems produce coherent radio bursts\, from the Jupiter-Io system to star-planet interactions to systems as exotic as long-period transients. While these bursts can look very different in terms of timescales and luminosity\, they all have something in common: an interaction with a companion. In this talk\, I will discuss the radio emission from stars\, brown dwarfs\, and long-period transients. I will cover observing strategies for these different types of transients as well as physical explanations for their emission\, showing that the fields of slow and fast transients overlap in more than just the name. \nWatch recording\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:CSIRO S&A Colloquium: Mattias Lazda (University of Toronto)
DESCRIPTION:The CHIME/FRB Outriggers: Project Overview and Commissioning Results\n\nAbstract \n\nThe CHIME/FRB Outriggers are a network of radio telescopes spanning continental North-America. Designed specifically for localizing fast radio bursts (FRBs) to <50 mas precision using very-long-baseline-interferometry\, the Outriggers will enable the precise localization of hundreds of non-repeating FRBs\, per year\, once fully operational. With the recent construction of the third and final outrigger now complete\, the Outriggers have officially unlocked the capability of precisely localizing non-repeating FRBs. In this talk\, I will provide an overview of the CHIME/FRB Outriggers project and a summary of the first stage of commissioning. By validating astrometric performance using a sample of known sources (e.g. pulsars and continuum sources)\, we show that the Outriggers can achieve a localization precision of 50 mas x 100 mas for a typical FRB event. I will discuss on-going efforts and upcoming plans to improve this ability to localize FRBs to the eventual goal of 50 mas x 50 mas precision for the majority of events detected by the CHIME/FRB Outriggers. I will close by highlighting the number of early science results that have been enabled by the Outriggers.  \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Erin Hestir (University of California\, Merced)
DESCRIPTION:Space-Based Tools for California’s Water Quality Challenges: Linking Satellites to Solutions\n\nMore than 3 billion people around the world lack access to reliable information about the quality of the water they drink. As wildfires\, drought\, and land degradation intensify\, our water systems face growing pressure—not just from scarcity\, but from worsening quality. Communities\, ecosystems\, and economies increasingly depend on timely\, science-based data to manage risks and build resilience. \n\nIn this seminar\, I will explore how satellite-based Earth observations are transforming the way we monitor\, understand\, and protect water quality. Drawing on case studies from across California\, I will demonstrate how spaceborne data are being used to detect harmful algal blooms and emerging contaminant\, assess the impacts of megafires and floods\, support habitat conservation\, and inform public health and resource management decisions. These tools are playing a growing role in bridging science\, technology\, and policy—offering decision-makers actionable insights to address both immediate challenges and long-term sustainability goals. \nJoin Event on Microsoft Teams\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Alex Cooper (University of Oxford)
DESCRIPTION:Magnetar Mysteries: Tales of Two Radio Transients\n\nMagnetars\, highly magnetized neutron stars\, are responsible for the most energetic transient events observed in the Milky Way. Their extreme magnetic environments enable exotic quantum processes\, such as spontaneous photon splitting and photo-magnetic electron-positron pair production\, providing unique avenues for testing fundamental physics under conditions not reproducible elsewhere in the universe. \n\nIn this talk\, I will examine two distinct classes of radio transients thought to be associated with magnetars: the recently discovered galactic Long Period Transients\, and extragalactic Fast Radio Bursts. I will present the observational evidence supporting the magnetar hypothesis\, discuss current theoretical models explaining how magnetars might produce these phenomena\, and outline the implications for our broader understanding of neutron stars and transient astronomy. I will conclude with the prospects for future research and discoveries in this rapidly evolving area of astrophysics. \n\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Ajay Kumar (NCRA\, Pune)
DESCRIPTION:Probing Fast Radio Bursts Using Deep Learning and GMRT\n\nFast Radio bursts are bright dispersed radio pulses of cosmological origin. Currently\, several hundred of them are known and published. The population of FRBs are classified as one-off events and repeaters. A small fraction of FRBs are active repeaters\, which can be studied in great detail to gain insights into their origins and emission mechanism. The discovery rate of FRBs is already a few per day and is expected to increase rapidly with new surveys coming online. The growing number of events necessitates prioritized follow-up due to limited multi-wavelength resources. \n\nI will describe Frabjous\, a deep learning framework for an automated morphology classifier\, with an aim towards enabling the rapid follow-up of anomalous and intriguing FRBs and a comprehensive statistical analysis of FRB morphologies. I will then discuss the results obtained from the application of Frabjous on simulated and first CHIME/FRB catalog and the potential for more accurate and reliable classification. \n\nI will also present the results from recent observational campaigns of several active repeaters\, including FRB 20220912A\, FRB 20240114A and FRB 20240619D using uGMRT. Furthermore\, I will describe their burst properties\, energy distributions\, host environments\, and temporal evolution of burst rates at lower radio frequencies. Finally\, I will discuss the implications of our results in the context of proposed progenitors models and emission mechanisms for repeating FRBs. \nJoin Event on Microsoft Teams\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:CSIRO S&A Colloquium: Connor Bottrell (UWA)
DESCRIPTION:Mini mergers with major consequences in a cold dark matter universe\n\nAbstract \n\nThe gravitational forces measured beyond the Solar System tell us that 85% of the matter in the Universe is invisible. But despite its abundance\, dark matter has so-far avoided direct detection by laboratory experiments on Earth. As a result\, particle physics theory has flourished to develop dark matter candidates that span a wide range of masses and phenomenologies. In this talk\, I will discuss some consequences of dark matter physics on galaxies including the predicted abundances of low-mass dark matter halos. In particular\, I will show that “mini” collisions with low-mass halos have an inconspicuously important role in driving diversity amongst large star-forming galaxies in cosmological simulations. These collisions are ubiquitous in the Cold Dark Matter cosmogony\, but suppressed by warmer\, lighter dark matter particles.  \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Erik Osinga (Dunlap Institute\, University of Toronto)
DESCRIPTION:Galaxy clusters as the Universe’s largest particle accelerators\n\nAbstract \n\nMergers of galaxy clusters represent the most energetic events since the Big Bang\, releasing energies up to 1064 ergs over Gyr timescales. This energy is dissipated through shocks and turbulence in the intra-cluster medium\, transforming clusters into the Universe’s largest laboratories for studying cosmic ray acceleration and magnetic field amplification. However\, our understanding has largely been limited to massive and nearby clusters due to observational constraints. In this talk\, I will show how observations at the longest wavelengths observable from the ground are revealing new insights into both turbulence and magnetic field amplification. Additionally\, I will discuss how advances in radio polarimetry and new surveys such as POSSUM are revealing the first detailed magnetic field structures within individual clusters. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquiaColloquia

SUMMARY:S&A Colloquium: Kana Morokuma
DESCRIPTION:Probing Radio-Mode AGN Feedback in NGC 1316: ALMA CO Mapping at GMA Scales\n\nActive galactic nuclei (AGN) feedback is essential for regulating the number density of massive galaxies. While radio-mode feedback is widely recognized for its large-scale impact\, suppressing cooling flows in the intracluster and intergalactic media to prevent gas accretion onto central galaxies\, recent simulations highlight a direct\, small-scale effect. Relativistic jets and their associated ionizing bubbles can inject turbulence into molecular clouds\, directly hindering star formation within galaxies. To investigate these effects\, we conducted high-resolution (100 pc) CO(J=1-0) mapping of a nearby radio galaxy NGC 1316 (Fornax A) using ALMA\, supplementing archival CO(J=2-1) and CO(J=3-2) data. Our analysis reveals: (1) a substantial contribution of single-dish data to the total CO(J=1-0) flux\, (2) the identification of approximately 20 giant molecular cloud associations with high velocity dispersions relative to their sizes\, suggesting gravitationally unbound structures\, (3) globally typical CO line ratios of R21 = CO(J=2-1)/CO(J=1-0)~0.7 and R31 = CO(J=3-2)/CO(J=3-2)~0.3 (in Kelvin units)\, and (4) elevated R21 and R31 values approaching unity within the central CO spectral wind. These findings provide observational evidence supporting theoretical predictions of AGN feedback on small scales. Furthermore\, the enhanced line ratios observed in the central region suggest that recent AGN activity is driving molecular gas outflow \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Ralf–Jürgen Dettmar
DESCRIPTION:Cosmic Ray Driven Galactic Winds\n\nNumerical models of the multiphase interstellar medium (ISM) in disk galaxies have recently addressed the importance of cosmic rays (CRs) and magnetic fields for the physics of the ISM. These components of the ISM contribute significantly to the total pressure and thus influence the large scale distribution of the ISM and its evolution. Observational evidence from radio-continuum studies of edge-on galaxies on magnetic field strength and structure will be presented and the cosmic ray propagation in galactic halos will be discussed. Observations from the CHANG- ES (Continuum HAlos in Nearby Galaxies – an EVLA Survey; PI J. Irwin) project benefit from complementary LOFAR observations. The lowest frequencies provide additional constraints on the extent of magnetic fields in galactic halos and on the synchrotron losses of the CR electrons. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Himanshu Tiwari
DESCRIPTION:Novel Interferometric Techniques for Detecting the 21-cm Signal from the Epoch of Reionisation\n\nDetecting the cosmological 21-cm signal from the Epoch of Reionisation (EoR) presents a significant challenge due to foreground contamination and instrumental limitations. Therefore\, alternative approaches can be explored to overcome some of these challenges. This work presents two independent approaches: Lunar Occultation for estimating the global 21-cm signal and closure phases for measuring the 21-cm power spectrum. Lunar Occultation utilises the Moon as a thermal reference to measure the foreground sky temperature\, with results demonstrated using Murchison Widefield Array (MWA) observations. A key aspect of this method is mitigating reflected FM Radio Frequency Interference (RFI) from the Moon\, which is addressed through modelling and statistical techniques. The second method employs radio interferometric closure phases to estimate the 21-cm power spectrum\, providing a calibration-independent alternative to traditional visibility-based methods. Our analysis of MWA data reveals systematic contaminants that impact sensitivity\, which are mitigated using statistical techniques. These methods lay basic foundation which can be beneficial for the upcoming radio experiments\, especially SKA-low\, to further our understanding of the early Universe through the 21-cm signal. \n\nLocation\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:Barbara Mazzilli Ciraulo's Colloquium
DESCRIPTION:Overview\n\nWinds and fountains in GECKOS star-forming galaxies \n\nDescribe the details of your eGalactic winds play a crucial role in galaxy evolution by expelling gas from the disk\, thereby limiting the fuel available for star formation. Simulations suggest these winds are the most important regulators of galaxy growth\, yet their mass outflow rates and phase distribution remain poorly constrained due to a lack of multi-phase observations spanning warm ionised\, cold molecular\, and atomic gas phases.I will present results from the GECKOS survey\, which combines deep VLT/MUSE observations with ALMA\, ASKAP-WALLABY and MeerKAT observations\, and upcoming JWST data to study galactic winds in edge-on galaxies. We resolve filamentary outflows from star-forming knots in the disk at ~100 pc scales. By quantifying the cold gas mass in these filaments across ionised\, molecular\, and atomic phases\, we estimate the energy required for feedback to lift this material. We relate star formation in the disk to the energy associated with feedback. Our results can directly inform sub-grid physics for galaxy evolution simulations and serve as a benchmark for large surveys of single-phase wind measurements. They also emphasise the critical role of multi-wavelength approaches in the upcoming SKA era.vent here … \n\n\nMS Teams\n\n\nkensington\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Di Li (Tsinghua University)
DESCRIPTION:A Tale of Two Surveys: Commensal Radio Astronomy FAST Survey (CRAFTS) and Cosmic Antennae (CA)\n\nAbstract \n\nAs first large-scale simultaneous survey of HI and pulsars， the Commensal Radio Astronomy FAST Survey (CRAFTS) has covered ~5000 d^2 of the northern sky\, roughly 25% of the sky visible to FAST. CRAFTS has discovered more than 200 new pulsars\, 10 new FRBs\, and released 4738 d^2 publication quality HI cubes\, with close to 1% calibration. CRAFTS revealed a FRB event rate at more than 120 K per day per full sky\, much more than previously realized. Such dynamic sky provides incentive for all sky radio monitor. Motivated by Ron Eker’s PAF concept\, we have developed the Cosmic Antennae phase-field imager explorer\, expecting first light in the coming months. This first generation CA will cover 600 MHz to 1.8 GHz with 112 probes x 2 polarizations\, resulting in a data rate close 1TB/s. The expected bursts detection rate will be about 1 per day. The next step will be fully deploying expanded CA\, aiming for instantaneously localization. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Vincenzo Galluzzi (IRA-INAF\, Bologna)
DESCRIPTION:From Data Archives to Science Gateways: examples of INAF-supported radio facilities.\n\nAbstract \n\nData archives are now rapidly evolving from simple repositories to sophisticated science gateways\, facilitating data discovery\, access\, retrieval\, visualization\, processing\, interoperability (with data at different wavelengths or from different messengers)\, and reuse. This transformation is driven by the increasing volume and complexity of data generated by modern radio astronomy facilities\, which offer unprecedented potential for scientific discovery. \n\nINAF has been at the forefront of this evolution\, actively embracing Open Science principles\, through supporting various initiatives promoted by the International Virtual Observatory Alliance (IVOA) in developing and implementing new standards. From the perspective of the radio astronomical facilities I am working with\, I will present some examples of e-infrastructures or projects at various scales\, including: \n\n\nThe INAF Radio Telescope Data Archive\, a newly operational archive providing access to a wealth of radio astronomical data. In such a context\, I will also briefly address the INAF contribution to the IVOA Radio Interest Groups (RIG)\, which recently proposed an extension of the ObsCore Data Model (ObsCore DM) for bolstering the discovery of radio data.\n\n\n\nThe Additional Representative Images for Legacy (ARI-L) project\, leaded by the Italian node of the ALMA Regional Centre: this project reprocessed ALMA data from earlier cycles (2-4) in order to support archival science projects\, hence adding value to the ALMA Science Archive (ASA) itself.\n\n\n\nThe deployment of the Italian node of the SKA Regional Centre Network (SRCNet): the Team Orange established by the SRC Steering Committee (SRCSC) has been working on a prototype for data visualization\, and recently changed its focus towards deployment activities\, since Italy will host one of the first 9 nodes of the SRCNet.\n\nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Bryan Scott (CIERA\, Northwestern University)
DESCRIPTION:Prospects for Fundamental Physics from Line Intensity Mapping\n\nAbstract \n\nLine Intensity Mapping (LIM) is a technique for quickly performing surveys of large volumes at many frequencies but at low spatial resolution. These large survey volumes make LIM a promising method for constraining fundamental physics\, such as beyond wCDM cosmology or extensions of Einstein Gravity in the coming decade. I will begin this talk with a presentation of LIM and synergies with photometric and spectroscopic galaxy surveys\, in particular the Vera C. Rubin Observatory Legacy Survey of Space & Time (LSST) and surveys with the Subaru Observatory Prime Focus Spectrograph (PFS). After introducing forecasting results for fundamental physics with LIM\, I will discuss how astrophysical uncertainties pose barriers to interpretation and conclude with an overview of prospects for machine learning and improved statistical methods to meet these challenges \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:Kristine Spekkens Colloquium
DESCRIPTION:Gas-Rich Galaxies as Cosmological Probes\n\n \n\nAbstract \n\nThe atomic gas (HI) content of nearby galaxies provides important insight into how they form and evolve within the standard cosmology. In this talk\, I will highlight some of my group’s recent progress towards building statistical samples of gas-rich galaxies to use as cosmological probes. I will first focus on how sensitive HI searches in optically-selected dwarf and ultra-diffuse galaxy candidates are a powerful tool for measuring their structure and constraining formation models. I will then describe how the widefield WALLABY survey\, now underway on the Australian SKA Pathfinder (ASKAP)\, is delivering the first spatially-resolved populations of HI disks for comparison with cosmological predictions. This work paves the way for probing HI disks across cosmic time using the SKA when it comes online towards the end of this decade. \nAdd a button here\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Michael Brown (Monash)
DESCRIPTION:Radio continuum emission from very massive galaxies\n\nAbstract\n\nSome of the first radio continuum radio sources to be identified were powerful radio-loud active galactic nuclei in very massive elliptical galaxies such as M87. As radio surveys have improved over the past seven decades\, an increasing fraction of massive elliptical galaxies have been found to host radio continuum sources. I will present recent work using the Australian Square Kilometre Array Pathfinder to search for radio continuum emission from local very massive galaxies without star formation. We find a very large fraction of very massive galaxies are radio continuum sources. However\, the radio powers of these sources can vary by orders of magnitude (at fixed galaxy mass)\, and there are some tantalising correlations between radio power\, morphology and host galaxy kinematics. \nWatch recording\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Meriem Behiri (SISSA)
DESCRIPTION:SHORES: Serendipitous H-ATLAS-fields Observations of Radio Extragalactic Sources with the ATCA\n\nAbstract\n\nIn this presentation\, we explore the advantages of integrating data from the radio to the far-infrared (FIR) spectrum for characterizing dusty star-forming galaxies (DS-FGs). These galaxies are believed to be the star-forming progenitors of local massive quiescent galaxies and are pivotal in reconstructing the cosmic star formation rate density up to high redshifts (Talia+21\,Enia+22\,Behiri+23). Due to their heavily obscured nature by dust\, DSFGs are often invisible in near-infrared/optical/UV bands\, necessitating observations at longer wavelengths\, primarily in the FIR band where dust emission occurs\, and in the radio band\, unaffected by dust absorption. By combining data from these spectral regions\, even the most dust-obscured objects can be characterized\, providing insights into their age\, dust temperature\, and star-formation activity\, and enabling differentiation between various galaxy populations evolving throughout cosmic history (Behiri+24). In this context\, we introduce the Serendipitous H-ATLAS fields Observations of Radio Extragalactic Sources (SHORES) survey. SHORES is a newly conducted survey at 2.1 GHz performed with the Australia Telescope Compact Array\, comprising 27 shallow fields and 2 deep fields centered around a candidate lensed galaxy. These fields are complemented by Herschel observations (H-ATLAS sgp) and data from various surveys (KIDS\, VIKING\, Euclid\, DES\, eRosita..)\, as well as SKAO pathfinders surveys (e.g.\, RACS). The extensive 200+ hours of observations with the ATCA interferometer have enabled us to achieve a 33 uJy rms for the shallow fields and 5 uJy rms for the deep fields\, resulting in a collection of more than 3200 sources. To fully characterize the radio spectra\, the SHORES deep field is observed at 5.5\, 9\, and 20 GHz\, providing crucial insights into various radio populations\, including Active Galactic Nuclei (AGN) and Star-Forming Galaxies (SFGs) (Behiri+\, in prep.). Additionally\, all SHORES observations incorporate polarization measurements\, offering a unique opportunity to explore the polarization nature across a substantial sample of AGN and SFGs (Galluzzi+\, in prep.). This comprehensive\, panchromatic approach provides a crucial perspective for unraveling the mysteries of the radio sky. The broad multi-wavelength coverage of the SHORES survey positions it as an ideal candidate for studying the diverse array of objects in the radio zoo\, thereby preparing us for forthcoming SKAO observations. \nWatch recording\nEvent details\nDownload iCal\nCategory\nColloquia

I will discuss a few of these cases (quasars\, pulsars and the galactic centre) in detail to illustrate how the path to discovery can be very different from the widely accepted scientific methodology. I will also comment on how the vision to explore the unknown has influenced the development of the SKA and its precursors.

DESCRIPTION:Constraining neutral hydrogen and its environment using radio interferometry\n\nAbstract\n\nIn this talk\, I will present an overview of my PhD research\, conducted over the past three and a half years as a CSIRO co-supervised student. My thesis investigates the relationship between neutral atomic hydrogen gas (HI) and its environment using radio interferometric observations. I will highlight my discovery of HI absorption in the brightest cluster galaxy (BCG) of the Norma cluster\, based on ATCA data\, which supports the BCG’s recent arrival into the cluster core. Additionally\, I will discuss my detection of 25 HI emission detections towards Norma using ASKAP data\, alongside my contribution to and findings from the optimisation of the WALLABY data-processing and HI source-finding pipelines in the presence of bright continuum sources. Finally\, I will contextualise my findings within a broader range of environments\, focusing on my analysis of the scatter in the HI-halo mass relation of central galaxies from the xGASS survey\, where I found a strong correlation with stellar specific angular momentum\, offering key insights for simulations. \nWatch recording\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:Colloquium: Rhea–Silvia Remus and Lucas Kimmig (LMU Munich)
DESCRIPTION:From Cosmic Dawn to Present-Day: Galaxy Formation and Evolution from Simulations\n\nAbstract: \n\nObservations of galaxies have revealed a puzzle of different properties seen from redshifts of z=10 or higher to present-day\, using multi-wavebands and integral field spectroscopy to probe the stellar light\, the gas\, but also infer the dark matter content of galaxies at different epochs of time. However\, as observations represent snapshots in time\, connecting the puzzle pieces in their evolution requires simulations to bridge our understanding of galaxy formation at early and late times. We will present the results of this endeavour using one of the largest sets of fully hydrodynamical cosmological simulations\, the Magneticum Pathfinder simulation suite and its adjacent simulations\, going from the earliest formation of galaxies to their present-day counterparts. We will highlight how metals in the stars reveal a galaxy’s assembly history\, show that most present day main sequence galaxies have experienced episodes of quiescence and rejuvenation\, and demonstrate how kinematics and low surface brightness features are connected. We invite you to join us on this journey of galaxy formation through cosmic time\, and discover how simulations and observations together shed light on how structures have formed in our Universe. \nTeams meeting\nPhysical location\n\nOnline location\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Dongjin Kim (CSIRO)
DESCRIPTION:Radio Jet and Obscuring Torus of Active Galactic Nuclei Revealed by VLBI\n\nAbstract\n\nActive Galactic Nuclei (AGNs) are believed to play a significant role in the formation and evolution of galaxies through their energetic jet outflows. However\, observational constraints are still limited when it comes to understanding how radio jets are triggered and how jet feedback operates in different types of AGNs. To gain insights into these processes\, it is crucial to study both the continuum radio jet and the circumnuclear gas in AGNs. This presentation will review high-angular-resolution VLBI studies on AGN radio jets and their immediate surroundings. Specifically\, I will emphasize spectroscopic studies of AGNs using molecular absorption and highlight promising scientific opportunities that can be achieved with current and future mm/sub-mm VLBI arrays. These studies provide valuable insights into the nuclear environments of AGNs\, offering a better understanding of the triggering and feedback mechanisms driving radio jet outflows. \nWatch recording\nEvent details\nDownload iCal\nCategory\nColloquia
