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: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: 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: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: 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: 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: 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: 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: 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:ATNF Futures 2030 Workshop 
DESCRIPTION:Overview\n\nThis workshop invites the Australian community to present science and technology ideas for the post-2030 era that deliver transformational advances with existing or upgraded facilities and new demonstrators in the SKA era. \n\nInyarrimanha Ilgari Bundara\, our Murchison Radio-astronomy Observatory is one of the best sites for radio astronomy observations in the world\, and the ATNF should take advantage of its unique environment. With SKA-Mid and SKA-Low telescopes coming online towards the end of the decade for science verification and full operations\, and DSA-2000 operating from the late 2020s\, it is timely for the community to start planning for post-2030 science and technology pathways. \n\nThe ASKAP telescope was built to: \n\n\nHelp establish an observatory site for the SKA Observatory’s SKA-Low telescope\, and\n\n\n\nDemonstrate SKA survey science technologies.\n\n\nFollowing the construction of ASKAP\, CSIRO ran an open proposal process\, and initiated the 5-year Science Survey Projects\, which are still in progress. \n\nThe first two aims have been achieved\, and the surveys are planned to be completed by the end of the decade. \n\nWe have supplied a document outlining a set of broad facility and technology concepts\, and the boundary conditions for the discussion. An ASKAP upgrade path is one of the concepts provided for discussion: \nConcept documentPDF450 KB\nWe will then invite abstracts for presentations that take one or more of these concepts and present a scientific and/or technology vision. These can be submitted via the registration form.  \n\nAims of the Workshop\n\n\nTo canvas ideas on the unique and world-leading science that ATNF can do in the 2030s\n\n\n\nTo bring the Australian community into the conversation about the future of mid-high frequency radio astronomy\n\n\n\nTo generate new ideas and collaborations within Australia and internationally.\n\n\nLocation\n\nIn-person at Marsfield and online \n\nRegistration\n\nAbstract submission has closed. Any abstracts proposed through the form will not be considered. Registration for in-person attendance has now closed.

SUMMARY:S&A Colloquium: Kovi Rose (University of Sydney) 
DESCRIPTION:Probing the Timescales of Radio Variability: From Late-time Supernovae Re-Brightening to Long Period Transients\n\nAbstract: \n\nWe have entered the age of big data in astrophysics and radio astronomy is no exception. Wide-field surveys with the Australian SKA Pathfinder (ASKAP) radio telescope are finding millions of radio-bright sources in the southern skies. In this talk I will speak about three recent discoveries and their implications on our understanding of stellar magnetism in fully convective stars\, binary evolution in accreting systems\, and the mass-loss history of supernova progenitors. The first comes from our detection of periodic bursts from an ultracool brown dwarf\, the latest spectral type star ever found to produce radio emission. Second\, we have found orbitally-modulated X-ray and radio pulses from a newly discovered long period transient. And finally\, we are finding supernovae re-brightening years after their optical discovery\, as the blast wave interacts with shells of circumstellar material. Finding and studying these rare transients is helping us explore astrophysical environments that cannot be studied on Earth. \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: Ashna Gulati (University of Sydney) 
DESCRIPTION:From Jets to Mergers: Multiwavelength Signatures of Synchrotron Transients\n\nAbstract: \n\nSynchrotron transients arise from some of the most energetic explosions in the Universe and trace the interaction of relativistic or sub-relativistic outflows with their surrounding environments. These interactions generate shocks that accelerate particles and amplify magnetic fields\, producing broadband synchrotron emission. While the underlying emission mechanism is broadly similar across sources\, differences in progenitor systems give rise to a wide range of outflow velocities\, energies\, and light-curve behaviours. Broadband observations are therefore a powerful tool for probing the physics of these extreme events\, from compact object interactions to stellar explosions. \n\nIn this talk\, I present results from three complementary approaches to studying synchrotron transients: targeted wide-field radio surveys\, untargeted extreme transient searches\, and rapid response follow-up. I discuss late-time ASKAP searches for radio afterglows from compact object mergers detected by LIGO–Virgo\, the discovery and detailed characterisation of the luminous and long-lived extragalactic radio transient ASKAP J0055–2558\, and a comprehensive radio-to-X-ray study of the exceptionally bright GRB 240825A. Together\, these studies demonstrate how broadband observations enable robust constraints on relativistic outflows and establish radio surveys and electromagnetic follow-up as a critical tool for exploring the extreme transient Universe in the SKA era. \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: Sam Taziaux (Ruhr University Bochum)
DESCRIPTION:MEDUSA  — Magnetic-field Evolution in Dwarf galaxies from Ultra-deep SKA Analysis  \n\n\nAbstract: \n\nDwarf galaxies are an important class of galaxies\, which are known to serve as proxy for the early Universe and play a crucial role in the formation and evolution of larger galaxies. To understand the underlying emission mechanism and the physics that drive the radiation far away from their origin\, we perform radio continuum polarimetry studies using deep MeerKAT observations. With the MEDUSA (Magnetic field Evolution in Dwarf galaxies Using SKA Analysis) project\, we present to-date the largest radio polarimetry study of dwarf galaxies\, including HI kinematics. Analysis of the spectrum reveals potential energy losses with rapid dissipation of electrons over kiloparsec scales\, a phenomenon contrasting sharply with observations from grand spiral galaxies. Furthermore\, small-scale dynamos in the star-fomation knots and a correlation between the level of depolarisation and the star formation histories deepen the understanding of this low mass systems. These findings provide evidence of intense material feedback into the intergalactic medium\, a process expected to be prevalent in the protogalaxies of the early Universe.  \n\nPlease note that the event timezone is AWST (UTC+8 hrs) \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\n \n\n \n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Jennifer West (Dominion Radio Astrophysical Observatory)
DESCRIPTION:Is the heliopause seen in radio synchrotron emission?\n\nAbstract: \n\nDiffuse radio synchrotron emission originating in the Milky Way fills the entire sky\, even at high Galactic latitudes. The emission is highly linearly polarised\, and comes from high energy CRs moving in the Galaxy’s magnetic field. Planck has measured the orientation of this emission and has mapped the magnetic field pattern across the sky\, however\, we do not know if the origin of the pattern is distant (tracing the large-scale magnetic field) or nearby (tracing the Local Bubble\, a massive superbubble where our Sun now resides). The reality is the emission must originate at a wide range of distances. In this talk\, I will present evidence that some of this emission has its origin in the interaction between the heliopause and the very local interstellar magnetic field. The emission is polarised\, and traces the local interstellar magnetic field as it wraps around the heliosphere at the heliopause boundary\, which is related to the Sun’s motion through space\, and which has previously been revealed through a bright ribbon of emission detected by NASA’s Interstellar Boundary Explorer (IBEX). \n\nPlease note that the event timezone is AEDT (UTC+11 hrs) \n\n \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia
