Discovery of radio eclipses from 4FGL J1646.54406: a new candidate redback pulsar binary
Andrew Zic, Ziteng Wang, Emil Lenc +9
Large widefield surveys make possible the serendipitous discovery of rare sub-classes of pulsars. One such class are "spider"-type pulsar binaries, comprised of a pulsar in a compa…
The Rapid ASKAP Continuum Survey V: cataloguing the sky at 1367.5 MHz and the second data release of RACS-mid
S. W. Duchesne, J. A. Grundy, George H. Heald +10
The Australian SKA Pathfinder (ASKAP) has surveyed the sky at multiple frequencies as part of the Rapid ASKAP Continuum Survey (RACS). The first two RACS observing epochs, at 887.5…
An off-axis relativistic jet seen in the long lasting delayed radio flare of the TDE AT 2018hyz
Itai Sfaradi, Paz Beniamini, Assaf Horesh +8
The Tidal Disruption Event (TDE) AT 2018hyz exhibited a delayed radio flare almost three years after the stellar disruption. Here we report new radio observations of the TDE AT 201…
Characterizing Pulsars Detected in the Rapid ASKAP Continuum Survey
Akash Anumarlapudi, Anna Ehlke, Megan L. Jones +16
We present the detection of 661 known pulsars observed with the Australian SKA Pathfinder (ASKAP) telescope at 888 MHz as a part of the Rapid ASKAP Continuum Survey (RACS). Detecti…
JWST detection of heavy neutron capture elements in a compact object merger
A. Levan, B. P. Gompertz, O. S. Salafia +80
The mergers of binary compact objects such as neutron stars and black holes are of central interest to several areas of astrophysics, including as the progenitors of gamma-ray burs…
A matched-filter approach to radio variability and transients: searching for orphan afterglows in the VAST Pilot Survey
James K. Leung, Tara Murphy, Emil Lenc +5
Radio transient searches using traditional variability metrics struggle to recover sources whose evolution timescale is significantly longer than the survey cadence. Motivated by t…
Detection of radio emission from stars via proper-motion searches
Laura Nicole Driessen, George Heald, Stefan W. Duchesne +4
We present a method for identifying radio stellar sources using their proper-motion. We demonstrate this method using the FIRST, VLASS, RACS-low and RACS-mid radio surveys, and ast…
The Rapid ASKAP Continuum Survey IV: continuum imaging at 1367.5 MHz and the first data release of RACS-mid
S. W. Duchesne, A. J. M. Thomson, J. Pritchard +15
The Australian SKA Pathfinder (ASKAP) is being used to undertake a campaign to rapidly survey the sky in three frequency bands across its operational spectral range. The first pass…
Classical Novae in the ASKAP Pilot Surveys
Ashna Gulati, Tara Murphy, David L. Kaplan +7
We present a systematic search for radio counterparts of novae using the Australian Square Kilometer Array Pathfinder (ASKAP). Our search used the Rapid ASKAP Continuum Survey, whi…
Precise Measurements of Self-absorbed Rising Reverse Shock Emission from Gamma-ray Burst 221009A
Joe S. Bright, Lauren Rhodes, Wael Farah +18
The deaths of massive stars are sometimes accompanied by the launch of highly relativistic and collimated jets. If the jet is pointed towards Earth, we observe a "prompt" gamma-ray…
