Evidence for the binary nature of the long-period radio transient ASKAP/DART J1832-0911
Csanád Horváth, Natasha Hurley-Walker, Ziteng Wang +2
Long-period transients are a class of periodic pulsed radio source repeating on the minute to hour timescale. Recently, an increasing number of them are being identified as binary…
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…
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 Rapid ASKAP Continuum Survey (RACS) VIII: total intensity and circular polarization images and catalogues at 887.5 MHz from RACS-low2
S. W. Duchesne, K. Rose, Tara Murphy +9
We present a new data release from the Rapid ASKAP Continuum Survey (RACS), a widefield snapshot radio survey conducted with the Australian SKA Pathfinder (ASKAP). This data releas…
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…
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…
Evolutionary Map of the Universe: A pilot survey to detect high Galactic latitude pulsars in variance images with ASKAP
A. Ahmad, S. Dai, E. Lenc +13
It has been proposed that radio pulsars can be distinguished from other point-like radio sources in continuum images by their unique interstellar scintillation signatures. Using da…
The Evolutionary Map of the Universe: A new radio atlas for the southern hemisphere sky
A. M. Hopkins, A. Kapinska, J. Marvil +70
We present the Evolutionary Map of the Universe (EMU) survey conducted with the Australian Square Kilometre Array Pathfinder (ASKAP). EMU aims to deliver the touchstone radio atlas…
Detecting Pulsars with Interstellar Scintillation in Variance Images
S. Dai, S. Johnston, M. E. Bell +4
Pulsars are the only cosmic radio sources known to be sufficiently compact to show diffractive interstellar scintillations. Images of the variance of radio signals in both time and…
