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

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
