SUMMARY:CSIRO S&A Colloquium: Mattias Lazda (University of Toronto)
DESCRIPTION:The CHIME/FRB Outriggers: Project Overview and Commissioning Results\n\nAbstract \n\nThe CHIME/FRB Outriggers are a network of radio telescopes spanning continental North-America. Designed specifically for localizing fast radio bursts (FRBs) to <50 mas precision using very-long-baseline-interferometry\, the Outriggers will enable the precise localization of hundreds of non-repeating FRBs\, per year\, once fully operational. With the recent construction of the third and final outrigger now complete\, the Outriggers have officially unlocked the capability of precisely localizing non-repeating FRBs. In this talk\, I will provide an overview of the CHIME/FRB Outriggers project and a summary of the first stage of commissioning. By validating astrometric performance using a sample of known sources (e.g. pulsars and continuum sources)\, we show that the Outriggers can achieve a localization precision of 50 mas x 100 mas for a typical FRB event. I will discuss on-going efforts and upcoming plans to improve this ability to localize FRBs to the eventual goal of 50 mas x 50 mas precision for the majority of events detected by the CHIME/FRB Outriggers. I will close by highlighting the number of early science results that have been enabled by the Outriggers.  \nJoin Event on Microsoft Teams\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Sanne Bloot (ASTRON / Kapteyn Astronomical Institute)
DESCRIPTION:From exoplanets to long-period transients: Coherent radio emission from binary systems\n\nAbstract\n\nMany binary systems produce coherent radio bursts\, from the Jupiter-Io system to star-planet interactions to systems as exotic as long-period transients. While these bursts can look very different in terms of timescales and luminosity\, they all have something in common: an interaction with a companion. In this talk\, I will discuss the radio emission from stars\, brown dwarfs\, and long-period transients. I will cover observing strategies for these different types of transients as well as physical explanations for their emission\, showing that the fields of slow and fast transients overlap in more than just the name. \nWatch recording\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Kshitij Bane (NCRA\, Pune)
DESCRIPTION:Under the SPOTLIGHT: Hunting Fast Transients in Real Time with the uGMRT\n\nAbstract:The detection of Fast Radio Bursts (FRBs) has grown exponentially in recent years\, but real-time localisation with high precision remains one of the key challenges in the field. SPOTLIGHT is a next-generation system developed at the upgraded Giant Metrewave Radio Telescope (uGMRT) to tackle this challenge. Operating commensally with regular uGMRT observations\, SPOTLIGHT employs a high-performance\, multi-node GPU cluster to handle petabyte-scale data processing in real time\, steering 2000 post-correlation beams at sub-millisecond resolution. \n\nPowered by an AI-driven transient detection pipeline\, SPOTLIGHT not only captures FRBs in real time but also triggers arcsecond-level imaging and raw voltage dumps for high-resolution studies across the 300–1460 MHz band. With its exceptional sensitivity\, SPOTLIGHT is expected to detect and localise hundreds of FRBs\, offering exciting prospects for understanding their origins. \n\nIn this talk\, I will present an overview of the SPOTLIGHT project\, its architecture\, performance\, recent tests\, and the scientific opportunities it unlocks. \n\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Piyush Mehta (CISER / West Virginia University)
DESCRIPTION:Next-Gen Tools and Techniques for Space Situational Awareness and Space Traffic Management\n\nAbstract:Space debris remains a persistent threat to assets and humans in space. The proliferation of low Earth orbit (LEO) with replenishable small satellite constellations driven by commercial interests has further stressed Space Situational Awareness (SSA) and put focus onSpace Traffic Management (STM). While the trackable debris catalog has grown significantly over the last decade\, lethal non-trackable (LNT) debris smaller than the order of centimeters in size remains a challenge as they fall below the detection and tracking capability of most ground-based sensors. In addition to catalog maintenance under SSA\, STM has put focus on enhanced and concerted space operations that includes conjunction assessment and collision avoidance. \n\nThe US Space Policy Directive-3\, National STM Policy has emphasized the necessity “to make significant contributions to establish a quality threshold for actionable collision avoidance warning to minimize false alarms”. Accurate calculation of Probability of Collision (PoC) for confident decision-making requires realistic covariance information since maneuvers are expensive (personnel cost\, science data or commercial service outage\, fuel costs). This talk will cover the work developing tools and algorithms targeted at addressing the challenge of LNT debris and enhancing LEO operations\, critical for a safe and sustainable space economy and environment. \n\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Rowina Nathan (Monash University)
DESCRIPTION:Understanding the gravitational wave background: pulsar timing arrays and skymapping\n\nAbstract:In June 2023\, members of the International Pulsar Timing Array (IPTA) released coordinated evidence for the gravitational wave background. In this seminar\, I will explain how pulsar timing arrays measure the gravitational wave background and discuss the latest results from various arrays.The MeerKAT radio telescope\, one of the most sensitive in the world\, has detected similar evidence after just 4.5 years of data collection through the MeerKAT Pulsar Timing Array. Thanks to its exceptional sensitivity and the new methods we have developed\, we have produced the most accurate maps of the gravitational-wave background to date. I will discuss our advances in skymapping methods and results. Mapping is crucial for understanding the origin of this background\, as an anisotropic background suggests supermassive black-hole binaries as the source. Notably\, we identify a hotspot in the 7 nHz map with a p-value of 0.015. \n\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Rick Perley (NRAO)
DESCRIPTION:Precision Meter-wavelength Polarimetry with the Jansky Very Large Array\n\nAbstract:Accurate polarimetry at meter-wavelengths requires correction of the ionospheric Faraday rotation measure (IFRM) with an accuracy better than 0.15 rad/m2.  In this talk I will show the results of testing of both global and regional estimates of the IFRM generated from GNSS timing data.   These tests used extensive polarimetric observations by the VLA and MeerKAT of the Moon\, the only source of polarized emission with an a priori known electric vector position angle distribution. \n\nWe find that all global estimates made from maps of the vertical total electron content (VTEC) by various agencies overestimate the IFRM for VLA observations by 0.3 to 1.0 rad/m2\, while a regional model\, utilizing GNSS data from stations near the VLA is much better\, with errors of typically 0.15 rad/m2.  This is sufficiently accurate for VLA observations at 300 MHz\, but not for lower frequencies.   \n\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia

SUMMARY:S&A Colloquium: Arpan Pal (NCRA\, Pune)
DESCRIPTION:When Clusters Collide and Telescopes Misbehave: My Life as a Radio Astronomer\n\nAbstract:When galaxy clusters collide at thousands of kilometers per second\, they create cosmic particle accelerators spanning millions of light years\, driving shocks that accelerate particles and amplify magnetic fields to produce diffuse radio emissions revealing the invisible architecture of these extreme environments. I’ll present low-frequency polarization observations of merging galaxy clusters using the upgraded Giant Metrewave Radio Telescope (uGMRT)\, supported by X-ray and high-frequency radio data from VLA and MeerKAT.  \n\nSurprisingly\, we found that low-frequency polarization does not follow high-frequency predictions\, with depolarization inconsistent with single-component magnetic field models. We present the first linear polarization detection below 1 GHz requiring multicomponent magnetic field distribution\, challenging conventional shock compression models in radio relics. However\, reliable polarization extraction proved challenging due to mysterious time-variable instrumental effects initially appearing astrophysical. Extensive systematic investigation of the telescope’s signal chain – involving months of debugging\, testing individual components from feeds to correlators\, and eliminating potential sources one by one – eventually identified an unexpected instrumental culprit responsible for these anomalous signals.  \n\nThis detective work highlights how instrumental systematics can masquerade as cosmic phenomena and I will walk through this technical adventure. To handle the massive data volumes from modern radio surveys\, we developed “Charizard\,” a fast radio imaging pipeline using aggressive parallelization strategies that processes terabytes of interferometric data orders of magnitude faster than traditional approaches. This speed enables more iterative analysis\, better systematics characterization\, and the ability to tackle larger statistical samples of merger systems. \n\nLocation\n\nOrganiser\n\nEvent details\nDownload iCal\nCategory\nColloquia
