Coherent radio bursts, polarity reversal, and quiescent emission from the M4V dwarf WW PsA
Jackson Mitchell-Bolton, Laura Driessen, Tara Murphy +6
Coherent radio emission from magnetically active M dwarfs is largely observed in two varieties: stochastic solar-like bursts and beamed, rotationally modulated emission including a…
Year-timescale changes in AGN radio luminosity as seen by the ASKAP Variables and Slow Transients Survey
Chloe Klare, Charlotte Ward, Dougal Dobie +6
A few dozen previously radio-quiet active galactic nuclei (AGN) have been observed to transition to radio-loud at 1-3 GHz frequencies over timescales of more than a decade, and thi…
Radio Properties of RS Canum Venaticorum Variables in VLASS and RACS
Suhasini S. Rao, Gregory R. Sivakoff, Craig O. Heinke +6
We performed a systematic search for radio emission from RS Canum Venaticorum (RS CVn) binaries, selected from the International Variable Star Index (VSX) catalog, in the Very Larg…
First monitoring campaign of a Main-sequence Radio Pulse emitter: the case of CU Vir
Barnali Das, Hayley Bignall, Andrew Zic +6
CU Vir, a magnetic hot star, is the first discovered Main-sequence Radio Pulse emitter (MRP) characterized by its ability to produce periodic radio pulses via electron cyclotron ma…
VASTER: The ASKAP real-time fast-imaging pipeline -- overview and discovery of two long period transients
Yuanming Wang, Dougal Dobie, Tara Murphy +22
Recent developments in widefield radio telescopes have enabled searches of a new region of parameter space in the time domain: timescales of seconds to minutes, that have been over…
The Variability of Radio Stars
Laura N. Driessen, Alex Andersson, Joseph R. Callingham +6
Stellar radio emission is highly variable with stellar flares lasting from milliseconds to hours. For some stars, their flares or bursts can repeat once every couple of hours, whil…
The X-ray emission of the long-period transient and accreting cataclysmic variable ASKAP J174508.9-505149
M. Imbrogno, M. Veresvarska, Y. L. Wang +8
Long-period transients (LPTs) challenge our knowledge of the mechanism producing radio periodic pulsations in compact objects. Some LPTs have been associated with systems hosting a…
Periodic Radio and X-ray Emission from an Accreting White Dwarf Binary
Kovi Rose, Joshua Pritchard, Tara Murphy +26
Long period radio transients (LPTs) are coherent bursts of polarised radio emission that repeat periodically on timescales of minutes to hours. Little is known about the physical o…
A sample of short-lived Galactic radio transients from ASKAP VAST
Akash Anumarlapudi, David L. Kaplan, Natasha Hurley Walker +6
Galactic radio transients (GRTs) are mysterious short-lived (~days to months) radio transients that are quiet at all other wavelengths. Until now, roughly half a dozen such sources…
One sightline, many systems: a FLASH discovery of HI towards scintillating quasar PKS 0405-385
E. F. Kerrison, H. Yoon, E. M. Sadler +15
We report the discovery of an intervening 21\,cm absorption line at z = 0.882 towards the z = 1.284 quasar PKS 0405-385, identified in the First Large Absorption Survey in HI (FLAS…
Discovery of a 36-minute long-period transient ASKAP J142431.2-612611
Joshua Pritchard, Tara Murphy, Dougal Dobie +13
We report the discovery of a new long-period radio transient, ASKAP J142431.2-612611, with a 36 minute period, identified in the Australian SKA Pathfinder Evolutionary Map of the U…
The ASKAP Variables and Slow Transients (VAST) Extragalactic Survey - Data Release 1
Iris de Ruiter, Dougal Dobie, Tara Murphy +13
The Variables and Slow Transients (VAST) Survey on the Australian SKA Pathfinder (ASKAP) is designed to systematically explore the dynamic radio sky, detecting sources that vary on…
ASKAP J005512.2-255834: A Luminous, Long-Lived Radio Transient at z = 0.1 -- an Orphan Afterglow or an off-nuclear TDE from an IMBH?
Ashna Gulati, Tara Murphy, David L. Kaplan +24
We report the discovery of a slowly evolving, extragalactic radio transient, ASKAP J005512.2--255834 (hereafter ASKAP J0055-2558), identified using the Australian SKA Pathfinder in…
