SUMMARY:S&A Colloquium: Joe Grundy (Curtin University)
DESCRIPTION:Investigating the Complex Radio Spectra and Infrared-Radio Correlation in Nearby Starforming Galaxies\n\nAbstract: \n\nIn my recently accepted thesis\, I examined the radio continuum emission of galaxies to determine how the physical processes that occur within galaxies modify the radio spectral energy distribution and physical distribution of radio emission. I studied the resolved radio continuum emission of 27 nearby star forming galaxies with facilities including MWA\, ASKAP\, ATCA and ALMA to examine the impact of cosmic ray electron energy loss and radio continuum absorption mechanisms as well as cosmic ray transport on the radio spectral energy distribution and their relations to a galaxies physical properties. I have also examined the relationships between radio continuum emission and star formation through the infrared to radio correlation and how these relationships are affected by physical processes within galaxies. Overall I find that the radio continuum emission of star forming galaxies is much more complex than simple two component synchrotron and free-free power law emission with factors such as ionisation losses\, synchrotron losses and free-free absorption impacting the radio emission differently in each galaxy depending on a galaxies size\, star formation rate and gas properties. A thorough understanding of the links between the physical properties of a galaxy and its radio spectral energy distribution is vital to be able to better calibrate radio star formation rate measures in preparation for future broad-band\, all-sky radio surveys with telescopes like the SKA. \n\nPlease note that the event timezone is AWST (UTC+8 hrs) \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Eric Burt (NASA/JPL\, 2025 IEEE Distinguished Lecturer on Frequency Control)
DESCRIPTION:Frequency Standard Contributions to Limitations on the Signal-to-Noise Ratio of Very Long Baseline Interferometry Observations\n\nAbstract: \n\nSince its observation in 2019\, the first image of a super-massive black hole using Very Long Baseline Interferometry (VLBI) between a network of Earth-based radio telescopes has generated much scientific and public interest\, including the possible extension to include one or more space-based radio antennas in order to obtain higher image resolution.  The VLBI technique assumes that each radio telescope has its own frequency standard or “clock\,” and a key requirement for that frequency standard is that it have sufficient stability and precision to enable the phase-coherent combination of signals from the independent radio telescopes.  For ground-based radio telescopes\, the state-of-practice is to have a hydrogen maser co-located.  The number of frequency standards that are both space-qualified and perform well enough for this type of VLBI is a small subset of those available on the ground.  Among these\, it will be necessary to determine what type of frequency standard performance is really required.  In addition\, given the high cost of launching instruments into space\, it may be necessary to make difficult trade-offs between instrument size\, and performance.  To facilitate this trade space\, we derive a metric that directly links frequency standard noise characteristics to the signal-to-noise (S/N) ratio as a function of averaging time for the central VLBI observable\, known as the “visibility.”  Using this metric\, we find that among the existing space clock candidates\, only an Ultra-Stable Oscillator (USO) and space hydrogen maser are potentially viable.  Furthermore\, a USO will only be effective for relatively short integration times for the high observational frequencies required\, which are typically of order 100 GHz or higher.  While a hydrogen maser can extend the averaging time\, it is likely to have prohibitive size and cost for a space VLBI node.  We also investigate emerging frequency standards\, including optical clocks\, and find that the best option may be the optical local oscillator used in an optical clock by itself without the atomic reference.  This approach can greatly reduce size and complexity of the frequency standard by eliminating the atomic reference while providing a limit on VLBI visibility S/N significantly higher than what is possible with a hydrogen maser. \n\nPlease note that the event timezone is AEDT (UTC+11 hrs)\, and it will be held at Payne Scott room instead of the lecture theatre. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Luca Ighina (Harvard Center for Astrophysics)
DESCRIPTION:A New Radio Window on the Growth of the First Supermassive Black Holes\n\nAbstract: \n\nFrom reionizing the Universe to quenching star formation in massive galaxies\, accreting supermassive black holes (SMBHs)\, or active galactic nuclei (AGN)\, are thought to play a pivotal role in early galaxy evolution. Growing observational evidence\, including recent results from JWST\, suggests that accreting black holes are both more abundant and more massive at than predicted by current theoretical models. In this talk I will present recent observational results on accreting black holes in the early Universe\, with a particular focus on radio-powerful AGN. I will show how relativistic jets can play an important role in both the rapid assembly of very massive black holes and the regulation of star formation in their host galaxies in the early Universe.  \n\nWhile exciting\, current studies focus on optically luminous AGN\, which likely represent only the tip of the iceberg of the SMBH population at early cosmic times. Heavily obscured AGN\, whose accretion signatures are hidden at optical and near-infrared wavelengths\, are predicted to dominate the high-z AGN population\, yet these sources remain largely unconstrained from an observational point of view. The synergy between next-generation radio and near-infrared wide-area surveys will soon open a new window on this elusive population. In particular\, radio observations can reveal the presence of relativistic jets\, and therefore ongoing black hole accretion\, even in systems that are obscured at optical wavelengths. The combination of ASKAP/EMU and EUCLID-wide surveys will provide the deepest multi-wavelength view of the extra-Galactic southern sky\, enabling the construction of the first large\, unbiased census of accreting black holes at z>6. As an example of the power of this synergy\, I will present a preliminary cross-match of EMU and Euclid over the EUCLID deep field South (∼25 deg2). \n\nPlease note that the event timezone is AWST (UTC+8 hrs) \n\n \n\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Matt Miles (Vanderbilt University)
DESCRIPTION:All Models Are Wrong: Noise Modelling in Pulsar Timing\n\nAbstract: \n\nPulsar timing arrays are only as good as the timing residuals they produce — and those residuals are only as clean as the method used to extract them. Traditional template-matching approaches measure pulse time-of-arrival (TOA) by fitting a single fixed or radio-frequency dependent template to observed profiles\, but this leaves a critical vulnerability: any stochastic variation in pulse shape is silently absorbed into the TOA as a systematic bias\, quietly corrupting the signals we are trying to extract. \n\nSCULPT is a new technique built of old ideas that fixes this at its source. By constructing a basis directly from observed profiles via SVD\, SCULPT learns the true structure of pulse shape variability from the data itself — no analytic assumptions\, no oracle knowledge required. Stochastic shape changes are absorbed into nuisance amplitude coefficients within this basis\, keeping them out of the timing solution. The result is a variational profile basis that is optimally adapted to the actual pulse morphology: expressive where it needs to be\, simple everywhere else. \n\nI will present the methodology behind this process and explore with the audience what it is we’re trying to achieve and why it’s an important goal. \n\nPlease note that the event timezone is AEDT (UTC+11 hrs) and will be held in the Faraday room \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Valentina Di Marco (University of Melbourne)
DESCRIPTION:All Models Are Wrong: Noise Modelling in Pulsar Timing\n\nAbstract: \n\nPulsar timing arrays\, like any experiment\, depend on accurate noise modelling to detect nanohertz gravitational waves. But the noise itself is much more complex than in some other experiments. It is multi-component and\, due to the astrophysical origin of several noise processes\, often uncertain and difficult to model accurately. In this talk\, I explore what happens when our noise models are wrong. \n\nI show that misspecified noise can bias gravitational-wave inference and distort spectral estimates. While these effects are sometimes conservative\, they can also lead to systematically incorrect conclusions\, highlighting the need to account for model uncertainty properly. \n\nI then present a transdimensional Bayesian approach for noise analysis that lets the data decide which noise processes are present in the signal. By jointly performing model selection and parameter estimation\, this framework provides a more robust and statistically consistent way to analyse pulsar timing data. \n\nPlease note that the event timezone is AEDT (UTC+11 hrs) \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Yuxiang Qin (Australian National University)
DESCRIPTION:Inferring properties of the first galaxies and intergalactic medium with 21-cm cosmology\n\nAbstract: \n\nThe redshifted 21-cm signal provides a unique probe of the first galaxies and their imprint on the thermal and ionization state of the intergalactic medium (IGM) during the Cosmic Dawn and Epoch of Reionization. In this talk\, I present a unified inference framework that jointly interprets constraints from low-frequency interferometers (e.g.\, HERA and MWA) and global-signal experiments such as EDGES\, in combination with complementary galaxy and CMB observations. \n\nBy jointly modelling these datasets\, we find converging evidence that the IGM was heated early\, ruling out a broad class of cold reionization scenarios and placing new constraints on the X-ray emissivity of the first galaxies. Within a galaxy-driven framework\, these results imply enhanced high-redshift X-ray production relative to local scaling relations\, potentially driven by metal-poor stellar populations and their remnants. In parallel\, global-signal analyses provide independent constraints on the timing and amplitude of the cosmic dawn signal\, and serve as a critical test of its astrophysical interpretation. \n\nAs these early sources are likely beyond the reach of direct detection\, even for facilities such as JWST\, the 21-cm signal remains a uniquely powerful probe of their collective impact. Looking ahead\, I will show how the Square Kilometre Array (SKA) will transform this field\, enabling precision constraints on the thermal history of the IGM and the properties of the first galaxies. \n\nPlease note that the event timezone is AWST (UTC+8 hrs) \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Georgia Stewart (University of Tasmania)
DESCRIPTION:Echoes of the Dying Light: The Evolution and Spectral Signatures of Simulated Remnant Radio Galaxies\n\nAbstract: \n\nRadio galaxy remnants are the quiescent phase of radio-loud active galactic nuclei (RLAGN) and provide key insight into AGN duty cycles and feedback. Observationally\, remnants are challenging to identify\, as their spectral and morphological properties often overlap with active sources\, necessitating multi-frequency data. \n\nIn my PhD\, I worked on the largest suite (to-date) of three-dimensional hydrodynamic simulations of active and remnant RLAGN evolving in realistic environments. Using synthetic radio emission generated from these simulations\, I investigated how jet power\, environment\, and active-phase duration shape the dynamics\, spectral evolution\, and observability of remnants. I showed that low-density environments delay the transition to buoyancy\, and high-powered sources sustain forward shocks that continue heating their surroundings. I also find several trends in the spectral evolution of remnants that are dependent on environment properties. \n\nI further explore remnant identification using machine learning on simulated radio data\, finding that even simple models can distinguish active and remnant sources\, though younger remnants are harder to classify. Finally\, I introduce a new method to calculate radio and X-ray observables directly from simulations\, enabling detailed\, high-resolution studies of lobe emission and its interaction with the environment. \n\nThese results provide a theoretical framework to interpret current and upcoming low-frequency surveys and improve our understanding of the lifecycle and impact of RLAGN. \n\n \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:Australasian "Orange" Pulsar Workshop 2026
DESCRIPTION:Overview\n\nThe Australasian “Orange” Pulsar Meeting is a fortnightly telecon\, supplemented by occasional in‑person workshops\, for the Australasian pulsar and FRB community that fosters collaboration between theorists\, modellers\, and observers. Following the successful 2022 Orange workshop at CSIRO’s Parkes Radio Observatory\, we are excited to host the next  in‑person meeting at the ATNF Marsfield Headquarters in Sydney from 5–7 May 2026. Online participation will be available for those unable to attend in person. \n\nThe workshop will take place at a time of progress and opportunity in pulsar and time‑domain radio astronomy. New instrumentation and facilities\, including the CryoPAF on Murriyang\, the Phase III upgrade of the MWA\, and the ongoing development of the SKA\, are expanding available discovery spaces. In parallel\, the ATNF is exploring potential future Australian radio astronomy facilities for 2030 and beyond. \n\nThis workshop aims to bring the community together to share recent advances in pulsar and time‑domain science\, discuss emerging scientific opportunities\, and to provide input to future (radio) astronomy strategy. \n\nWorkshop schedule\n\nAustralasian_Orange_Workshop_2026_Sched_v2Download\n\nLocation\n\nOrganiser\n\nScience Organising Committee\n\n\nAndrew Zic (CSIRO)\n\n\n\nManisha Caleb (USyd)\n\n\n\nEmma Carli (Swinburne)\n\n\n\nJoscha Jahns-Schindler (Swinburne)\n\n\n\nBradley Meyers (AusSRC)\n\n\n\nNicholas O’Neill (UMelb)\n\n\n\nRyan Shannon (Swinburne)\n\n\n\nChia Min Tanh (Curtin)\n\n\nEvent details\n\n \nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Prof Yihua Yan (National Astronomical Observatories\, Chinese Academy of Sciences)
DESCRIPTION:Overview on Chinese Meridian Project – Solar and Heliospheric Radio Studies at Mingantu Observing Station\n\nAbstract: \n\nThe Chinese Meridian Project (CMP) is a Ground‐based Space Environment Monitoring Network which includes the Space Environment Monitoring System. The system adopts a well‐designed monitoring architecture\, known as “One Chain\, Three Networks\, and Four Focuses” to achieve stereoscopic and comprehensive monitoring of the entire solar-terrestrial space. The “One‐Chain” component utilizes optical\, radio\, interplanetary scintillation\, and cosmic ray instruments to cover the causal chain of space weather disturbances from the solar surface to near‐Earth space. For the ionosphere\, middle and upper atmosphere\, and geo-magnetic field\, instruments are deployed along longitudes of 120o and 100oE\, and latitudes of 30o and 40oN\, forming the “Three Networks”. Furthermore\, more powerful monitoring facilities or large‐scale instruments have been deployed in four key regions: the high-latitude polar region\, mid‐latitude region in northern China\, low‐latitude region at Hainan Island\, and the Tibet region. These four regions are crucial for disturbances propagation and evolution\, or possess unique geographical and topographical characteristics. \n\nThe Mingantu Observing Station\, which is located about 400km northwest of Beijing with the wide‐band spectral radioheliographs and the interplanetary scintillation telescopes\, constitutes a key component of CMP for tracking and monitoring solar eruptions from the Sun’s atmosphere into interplanetary space. Here we give an overview on CMP and introduce the progress on solar and heliospheric radio studies at Mingantu Observing Station. \n\nPlease note that the event timezone is AWST (UTC+8 hrs) \n\nLocation\n\nOrganiser\n\n\n \n\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Georgios Paraschos (University of Turku)
DESCRIPTION:Shocks\, polarisation\, and high-energy emission: Probing black hole jets from VLBI to IXPE\n\nAbstract: \n\nRelativistic jets launched by accreting supermassive black holes are fundamental drivers of feedback in galaxies\, yet the location and mechanisms responsible for high- energy γ-ray emission remain uncertain. I will present recent multimessenger studies combining VLBI imaging\, IXPE X-ray and optical polarimetry\, γ-ray monitoring\, and neutrino observations of blazars undergoing major flaring events. These coordinated campaigns reveal shock–shock interactions in the parsec-scale jet\, conditions favourable for hadronic emission\, and γ-ray production occurring well downstream of the central engine. I will discuss these results in the context of our broader efforts with the Event Horizon Telescope to directly probe the physical conditions governing jet formation and high-energy radiation near supermassive black holes. Finally\, I will touch upon the collaborative work planned with colleagues at the ATNF. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:FLASH Splash: Celebrating the completion of observations
DESCRIPTION:Overview\n\nCSIRO invites our ATNF colleagues and collaborators to celebrate the ASKAP radio telescope’s completion of observations for the FLASH survey. \n\nFLASH (First Large Absorption Survey in HI)\, looks for areas where a bright background light filters through hydrogen gas to analyse the gas’ characteristics. With hydrogen gas the raw material from which new stars are formed\, the completion of these observations is a major milestone in our understanding of galaxy evolution. \n\nJoin us as we recognise the dedication of the scientists\, engineers\, and support staff throughout CSIRO and the FLASH team who made this achievement possible. \n\nThe event will include a brief overview of the survey’s journey and early highlights\, followed by refreshments and an opportunity to reflect on the science enabled – and the discoveries still to come. \n\nWe acknowledge the Wajarri Yamaji as the Traditional Owners and Native Title Holders of the Inyarrimanha Ilgari Bundara\, our Murchison Radio-astronomy Observatory site\, where ASKAP is located. \n\nDetails \n\nWhen: 14 May 2026 \n\nTime: 1:00pm – 2:45pm AEST / 11:00am – 12:45pm AWST \n\nLocation: Marsfield (Lecture Theatre)\, Kensington (Auditorium)\, Geraldton (MSF Conference Room)  \nRegister\nPlease refer to the event’s webpage for further details  \n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Xiaohui Sun (Yunnan University)
DESCRIPTION:Study of Galactic multi-scale magnetic field with radio polarization observation\n\nAbstract: \n\nRadio polarization observation provides an important way to study Galactic magnetic field from small to large scales. All-sky polarization surveys with broad frequency coverage are well suited for the study. In this talk\, I present recent studies on supernova remnants and pulsar wind nebulae from ASKAP and ATCA observations. I will then present the results from the STAPS survey conducted with Murriyang and ongoing FAST observations. To the low frequency end\, the polarization images from MWA reveal large-scale structures likely originated from local interstellar medium. I will conclude the talk with a perspective with future SKA. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Lindsey Oberhelman (ANU)
DESCRIPTION:The turbulent magnetic Milky Way\, deriving a turbulent field scale height from POSSUM data\n\nAbstract: \n\nUsing broadband polarimetric observations from the ASKAP POSSUM survey\, I investigate the turbulent magnetised interstellar medium of the Milky Way through Faraday complexity in more than 37\,000 polarised extragalactic radio sources. By applying QU-fitting to the Stokes Q and U spectra\, I measure Faraday broadening\, which traces fluctuations in the line-of-sight magnetic field and thermal electron density. I examine the Galactic latitude dependence of turbulence and interpret the results using the exponential disk model. The results also suggest a possible north–south asymmetry in the turbulent foreground\, potentially linked to Galactic structure\, spiral arms\, warp\, or the Magellanic system. I discuss the role of turbulence correlation length assumptions\, comparisons with pulsar scintillation and RM structure-function studies\, and ongoing work using RM structure functions to constrain the physical scales of turbulence probed by POSSUM.  \n\nPlease note that the event timezone is AWST (UTC+8 hrs) \n\nLocation\n\nOrganiser\n\n\n \n\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:2026 Radio School
DESCRIPTION:Overview\n\nThe ATNF Radio School 2026 is an immersive training program designed for PhD students\, postdoctoral researchers and early career astronomers who want to build solid foundations in radio interferometry and hands-on data skills. Hosted by CSIRO’s Australia Telescope National Facility (ATNF) at the Paul Wild Observatory on Gomeroi Country\, near Narrabri\, NSW\, this year’s school blends core theory with practical calibration and imaging tutorials at one of Australia’s premier radio astronomy facilities. The site is home to our Australia Telescope Compact Array (ATCA). \n\nOver the course of the week\, participants will learn the fundamentals of radio interferometry\, antenna calibration\, data flagging and imaging through a mix of expert-led lectures and interactive\, practical sessions. Unique to 2026\, the program will feature tutorials making use of ATCA’s new Broadband Integrated GPU Correlator (BIGCAT)\, the next-generation correlator system that significantly expands ATCA’s instantaneous bandwidth and data flexibility\, giving attendees early experience with cutting-edge correlator operations and data pipelines.  \n\nThe 2026 Radio School is aimed at PhD students and postdoctoral researchers in astronomy. The Radio School offers a supportive environment to engage deeply with real interferometric data\, develop essential calibration and imaging workflows\, and connect with leaders in the field. No prior experience with radio astronomy is required. \n\nFor those students who are unable to attend the Radio School in-person in Narrabri\, a virtual option will be available for the lectures. \n\nInformation regarding the 2026 Radio School can be found on the School’s webpage. \nRegister\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal

SUMMARY:S&A Colloquium: Dr Konstantinos Kolokythas (Rhodes University and SARAO)
DESCRIPTION:From Group Dynamics to Cluster Halos: A Multi-Band View of Galaxy Evolution in Groups and the Diffuse Skies in Clusters \n\nAbstract: \n\nMuch of the evolution of galaxies before they are assimilated into clusters occurs in groups where AGN feedback has the greatest impact on galaxy formation and evolution. Conversely\, clusters are the largest gravitationally bound structures in the Universe\, with radio observations being powerful tools for detecting diffuse cluster-scale synchrotron emission\, which conveys information about the cluster formation history. In the first part of this talk\, I will summarize results from studies of the central brightest group early-type galaxies (BGEs) of an optically selected\, statistically complete sample of 53 nearby groups (<80 Mpc; CLoGS sample)\, observed in radio 235/610 MHz (GMRT)\, CO (IRAM/APEX) and X-ray (Chandra and XMM-Newton) frequencies examining the balance between hot and cold gas (AGN feedback) and the AGN activity and star formation in groups\, presenting also updated results from MeerKAT L-Band observations.  In the second part\, I will summarise results from the recently published MeerKAT’s Galaxy Cluster Legacy Survey (MGCLS) diffuse radio emission catalogue work (Kolokythas et al. 2025)\, a project which originally comprised the first MeerKAT L-Band long-track observations of 115 galaxy clusters at 1.28 GHz across the Southern sky. I will focus on the discoveries and properties of the various diffuse radio emission structures detected in MGCLS galaxy clusters\, which reveal new areas of investigation in cluster formation and evolution that pave the way for the SKA era.  \n\nPlease note that the event timezone is AWST (UTC+8 hrs) \n\nLocation\n\nOrganiser\n\n\n \n\n\nEvent details\nDownload iCal\nCategory\nColloquia
