SUMMARY:S&A Colloquium: Simon Ho (ANU)
DESCRIPTION:Fast Radio Transients in the nearby Universe\n\nAbstract: \n\nMotivated by the discovery of a repeating FRB associated with a globular cluster in the nearby galaxy M81\, this talk explores the origins of fast radio transients in old stellar environments and examines the relationship between FRBs and giant radio pulses (GPs) from neutron stars. Using MeerKAT ultra-high frequency (UHF) baseband observations of the millisecond pulsar PSR J1823-3021A in the globular cluster NGC 6624\, we detect more than 3.7×10^4 GPs per hour\, establishing it as one of the most prolific GP emitters known. Although the pulses exhibit complex temporal and spectral structures\, their energetics\, periodicity\, and statistical properties distinguish them from FRBs\, suggesting that GPs are unlikely to be direct low-energy analogues of the FRB population. We also investigate scintillation and coherent descattering\, demonstrating the feasibility of recovering intrinsic pulse structures from giant pulses in J1823-3021A. Extending this work to extragalactic systems\, we conduct a deep FAST search for FRBs from globular clusters in the nearby elliptical galaxy M49 (NGC 4472)\, covering ~4000 globular clusters. No FRBs are conclusively detected\, yielding stringent upper limits on FRB activity in globular clusters. Lastly\, in this talk\, I will briefly present the current status of the Bustling Universe Radio Survey Telescope in Taiwan (BURSTT)\, which is a dedicated survey aiming to search for FRBs in the nearby universe with its extremely wide field of view (~10\,000 square degrees). \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:Colearnium: Phil Collins & Ali Wilson (CSIRO)
DESCRIPTION:“Psychosocial – Procedure awareness”\n\nThis week Phil Collins & Ali Wilson will cover “Psychosocial – Procedure awareness“. \n\n“As part of the HSE Plan 25-27 and our values of ‘Further Together’ the CSIRO HSE ‘Grassroots Campaign’ has a focus on HSE Procedure Awareness.    \n\nThe HSE Team is working together to develop the information for these sessions which will be delivered by the HSE Manager from each RU. This invitation is open to all Space and Astronomy Staff. \n\nThe sessions themselves will be an overview of the procedure\, followed by discussion and opportunity for questions. \n\nTo get the most from attending the session read the procedure prior to attending  – Psychosocial Safety Procedure – MyCSIRO (internal link). \n\nSubject Matter Experts will be in the sessions or provide content (where relevant and available) to add specific insight into the discussions.” \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\nStefan Duchesne \n\nTeams meeting link below: \nTeams Meeting\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Hariharan Krishnan (SKAO)
DESCRIPTION:Enabling Next-Generation Solar and Heliospheric Science with SKA-Low Signal Processing\n\nAbstract: \n\nThe Square Kilometre Array-Low (SKA-Low) telescope represents a transformative leap forward for low-frequency radio astronomy. Operating across the 50–350 MHz band with 131\,072 dual-polarization log-periodic dipole antennas grouped into 512 Low-Frequency Aperture Array (LFAA) stations\, the array presents unprecedented digital signal processing challenges. At the heart of this system lies a tightly integrated digital signal chain. Within the Signal Processing Subsystem (SPS)\, broadband analog RF signals from the antenna are digitized at high dynamic range and channelized through a polyphase filterbank producing coarse frequency channels that optimise data transport efficiency for the station beamformer module. The ensemble of station beams are then processed by the Central Signal Processor (CSP) Correlator and Beamformer (CBF) to generate full-polarization visibilities for high-fidelity imaging and narrow\, high-time-resolution tied-array beams. \n\nThis talk provides an overview of how this signal chain architecture interfaces with frontier solar and heliospheric observations. SKA-Low’s dense short-baseline configuration and broad instantaneous bandwidth offer the raw capability for sub-second imaging spectroscopy of impulsive solar radio emission and Coronal Mass Ejections (CMEs)\, alongside high-cadence observations of interplanetary scintillation (IPS) to probe the dynamic solar wind. However\, physical interpretation in this low-frequency regime is intrinsically shaped by propagation effects\, including scattering\, refraction\, and magneto-ionic mode coupling within the coronal plasma. I will outline the direct mapping between the Low telescope digital signal processing capabilities and the science enabled in the solar and heliospheric context\, while highlighting the resulting limits on physical inference. \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia
