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\nColearnia

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\nColearnia

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\nColearnia

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\nColearnia

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\nColearnia

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\nColearnia

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\nColearnia

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\nColearnia

SUMMARY:S&A Colloquium: Rick Perley (NRAO)
DESCRIPTION:Precision Meter-wavelength Polarimetry with the Jansky Very Large Array\n\nAbstract:Accurate polarimetry at meter-wavelengths requires correction of the ionospheric Faraday rotation measure (IFRM) with an accuracy better than 0.15 rad/m2.  In this talk I will show the results of testing of both global and regional estimates of the IFRM generated from GNSS timing data.   These tests used extensive polarimetric observations by the VLA and MeerKAT of the Moon\, the only source of polarized emission with an a priori known electric vector position angle distribution. \n\nWe find that all global estimates made from maps of the vertical total electron content (VTEC) by various agencies overestimate the IFRM for VLA observations by 0.3 to 1.0 rad/m2\, while a regional model\, utilizing GNSS data from stations near the VLA is much better\, with errors of typically 0.15 rad/m2.  This is sufficiently accurate for VLA observations at 300 MHz\, but not for lower frequencies.   \n\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColearnia

SUMMARY:S&A Colloquium: Arpan Pal (NCRA\, Pune)
DESCRIPTION:When Clusters Collide and Telescopes Misbehave: My Life as a Radio Astronomer\n\nAbstract:When galaxy clusters collide at thousands of kilometers per second\, they create cosmic particle accelerators spanning millions of light years\, driving shocks that accelerate particles and amplify magnetic fields to produce diffuse radio emissions revealing the invisible architecture of these extreme environments. I’ll present low-frequency polarization observations of merging galaxy clusters using the upgraded Giant Metrewave Radio Telescope (uGMRT)\, supported by X-ray and high-frequency radio data from VLA and MeerKAT.  \n\nSurprisingly\, we found that low-frequency polarization does not follow high-frequency predictions\, with depolarization inconsistent with single-component magnetic field models. We present the first linear polarization detection below 1 GHz requiring multicomponent magnetic field distribution\, challenging conventional shock compression models in radio relics. However\, reliable polarization extraction proved challenging due to mysterious time-variable instrumental effects initially appearing astrophysical. Extensive systematic investigation of the telescope’s signal chain – involving months of debugging\, testing individual components from feeds to correlators\, and eliminating potential sources one by one – eventually identified an unexpected instrumental culprit responsible for these anomalous signals.  \n\nThis detective work highlights how instrumental systematics can masquerade as cosmic phenomena and I will walk through this technical adventure. To handle the massive data volumes from modern radio surveys\, we developed “Charizard\,” a fast radio imaging pipeline using aggressive parallelization strategies that processes terabytes of interferometric data orders of magnitude faster than traditional approaches. This speed enables more iterative analysis\, better systematics characterization\, and the ability to tackle larger statistical samples of merger systems. \n\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColearnia

SUMMARY:Colearnium: David Skellern
DESCRIPTION:A commentary on who really ‘invented Wi-Fi’\n\nThis week David Skellern will present on “A commentary on who really ‘invented Wi-Fi’“. \n\n———————————————————————————————————————————————————– \n\nDr David Skellern\, AO FTSE FIEEE HonFIEAust \n\nDr David Skellern worked in radio astronomy for 10 years and taught electronics at the University of Sydney and Macquarie Universities for 16 years before coming to prominence in the IT sector through Radiata\, which he co-founded in 1997. Building on joint research at Macquarie University and CSIRO\, Radiata demonstrated the world’s first chip-set implementation of the 54Mbit/s lEEE 802.11a high speed WLAN standard. Radiata was sold in 2001 to Cisco Systems Inc\, where Dr Skellern was Director\, Technology of the Wireless Networking Business Unit until 2004.  \n\nHe was appointed to the Board of National ICT Australia in 2003 and was Chief Executive Officer 2005-2010.   \n\nHe was a Non-executive Director (NED) of the Board of the Capital Markets CRC (CMCRC) 2004-2019 and Board Chair 2013-2019\, then Chair of RoZetta Institute Ltd (formerly CMCRC) 2019-2022. He was also a NED of the Boards of eight RoZetta Group companies.  \n\nDr Skellern is a NED and Board Chair of Quasar Satellite Technologies Pty Ltd\, the Semiconductor Sector Service Bureau (S3B)\, and the International Centre for Radio Astronomy Research (ICRAR)\, and a NED of Trovio Pte Ltd. He advises several early-stage technology companies. He is a Visiting Professor at Imperial College London and an Adjunct Professor at Macquarie University.   \n\nWho Really Invented Wi-Fi? \n\nIn the early 1990s\, a joint CSIRO/Macquarie University team conceived\, developed and implemented the linked technologies that made it possible to scale wireless LANs to ever-higher speeds as chip technology advanced. This pioneering work shaped the global success of Wi-Fi.  \n\nA Sydney Morning Herald article on March 25 this year mixed valid concerns on science funding innovation with selective history and emphasis on disputes to downplay and reframe the originality and significance of these Australian achievements on high speed WiFi.  \n\nThis talk sets the record straight\, separating fact from myth\, and showing how high-speed WiFi was truly born. \n\n———————————————————————————————————————————————————– \n\n \n\nPlease let me know if you’re willing to present at a future co-learnium or have requests for specific talks\, thanks! \n\nKind regards\, \n\nSamuel (On behalf of the co-learnium organisers) \n\nTeams meeting link below: \nTeams Meeting\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColearnia

SUMMARY:S&A Colloquium: Iris de Ruiter (University of Sydney)
DESCRIPTION:The Variables and Slow Transients Extragalactic survey: exploring radio transients with ASKAP \n\nAbstract:  \n\nThe Variables and Slow Transients (VAST) survey on the Australian Square Kilometre Array Pathfinder (ASKAP) is transforming our view of the dynamic radio sky. For decades\, searches for radio transients typically yielded only a handful of detections. Today\, wide-field\, sensitive telescopes like ASKAP have transformed our view of the dynamic radio sky. With VAST\, we are monitoring millions of sources and building light curves on an unprecedented scale. \n\nIn this talk I will present an update on the extragalactic component of VAST. I will outline our observing strategy\, data processing and quality control\, and describe how we build and interpret light curves. Finally\, I will showcase results from the 100 most variable sources in our current sample—just the beginning of what this rich dataset can reveal. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColearnia

SUMMARY:S&A Colloquium: Chenoa Tremblay (SETI / Breakthrough)
DESCRIPTION: Large-Scale Technosignatures Searches and the Stuff that Makes it Work\n\nAbstract: The search for technological life beyond Earth is a large-scale search for unidentified spectral-temporal signatures. So far\, most searches for these electromagnetic “technosignatures” have required dedicated time on telescopes or the use of archival data. A new digital back-end for the Karl G. Jansky Very Large Array (VLA) and the MeerKAT telescopes has been developed to continuously observe the sky during observations and process the data in real-time to detect these unique signals. The systems named COSMIC (the Commensal Open-source Multimode Interferometric Cluster) and BL USE employ Ethernet packet protocols\, real-time calibration strategies\, coherent and incoherent beamforming\, and open-source Doppler search algorithms to complete this goal at high-time and high-frequency resolutions. In collaboration with NRAO and the VLA sky-survey team\, we are recording during epoch 4 of the survey for one of the first all-sky searches for extraterrestrial signals\, with the sensitivity improvements allowed by such a powerful telescope. The purpose of this talk is to present the hardware and software structures of COSMIC and BL USE\, how they function\, and our first results. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColearnia

SUMMARY:S&A Colloquium: Aline Vidotto (Observatory of Leiden University\, Netherlands)
DESCRIPTION:Exo-space weather: The impact of stellar activity and outflows on exoplanets\n\nAbstract:  \n\nActivity of cool dwarf stars can reveal itself in the form of high-energy radiation (eg\, enhanced X-ray coronal emission\, flares) and particles (eg\, winds\, coronal mass ejections). Together\, these phenomena shape the space weather around (exo)planets. Because most of the known exoplanets have significantly closer orbital distances than solar system planets\, they are often embedded in much harsher particle and radiation environments\, leading to stronger interactions between the exoplanet and its surrounding environment.In this talk I will present some of our recent modelling efforts investigating how stellar activity and outflows can induce and shape atmospheric escape in exoplanets. I will also present the other side of the story: how (and when) exoplanets can affect the host star\, in particular\, focusing on radio emission that exoplanets can induce in the coronae of stars. Altogether\, these interactions can help us characterise the system\, putting physical constraints on planetary properties (such as their still elusive magnetic fields) as well as properties of the winds of planet hosting stars. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColearnia

SUMMARY:S&A Colloquium: Emma Carli (Swinburne University)
DESCRIPTION:Are neutron stars outside our galaxy any different?\n\nAbstract: \n\nThe TRAPUM  (TRAnsients and PUlsars with MeerKAT) collaboration has so far doubled the extragalactic radio pulsar population with a survey of nearby galaxies.The completed Small Magellanic Cloud (SMC) galaxy survey revealed a large proportion of neutron stars in this star-forming dwarf are young\, including new Pulsar Wind Nebulae systems\, as well as giant pulsar glitches and Vela-like behaviour. The prolific Large Magellanic Cloud survey is still under way.This prompted a new project to study the whole Neutron Star population of the SMC as a nearby template for the high-redshift\, low-metallicity\, star-forming dwarf galaxies that are producing hyperactive Fast Radio Bursts\, exotic supernovae\, gamma-ray bursts\, and large High-Mass X-ray Binary populations. I will present the implications of this project and our initial investigations. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColearnia

SUMMARY:S&A Colloquium: Ravi Subrahmanyan (CSIRO)
DESCRIPTION:Radio discovery of Cosmic Dawn\n\nAbstract \n\nAs First Light from the First Stars transforms the universe from Dark Ages into Cosmic Dawn\, the thermal history may be traced in redshifted 21-cm from neutral hydrogen in the gas.  Efforts to build radiometers  to detect this faint signal are yielding results of significance to the theory\, thus constraining the starlight of the earliest galaxies and their impact on the gas.  I will present the progression in astrophysical constraints that have resulted from radiometers deployed in remote sites in India – at the Timbaktu collective\, in the trans-Himalayan plateau and floated on remote lakes.   Progress in precision has led to building of a GINAN radiometer in CSIRO\, which has been trialed at the Inyarrimanha Ilgari Bundara\, the Murchison Radio-astronomy Observatory in remote radio-quiet Western Australia\, with an SKA-Low antenna element. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColearnia
