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: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
