The dense and non-homogeneous circumstellar medium revealed in radio wavelengths around the Type Ib SN 2019oys
Itai Sfaradi, Assaf Horesh, Jesper Sollerman +7
We present here broadband radio observations of the CSM interacting SN2019oys. SN2019oys was first detected in the optical and was classified as a Type Ib SN. Then, about $\sim 100…
Commensal Transient Searches in Eight Short Gamma Ray Burst Fields
S. I. Chastain, A. J. van der Horst, A. Rowlinson +5
A new generation of radio telescopes with excellent sensitivity, instantaneous {\it uv} coverage, and large fields of view, are providing unprecedented opportunities for performing…
AT2022aedm and a new class of luminous, fast-cooling transients in elliptical galaxies
M. Nicholl, S. Srivastav, M. D. Fulton +49
We present the discovery and extensive follow-up of a remarkable fast-evolving optical transient, AT2022aedm, detected by the Asteroid Terrestrial impact Last Alert Survey (ATLAS).…
FRB 20121102A: images of the bursts and the varying radio counterpart
L. Rhodes, M. Caleb, B. W. Stappers +4
As more Fast Radio Bursts (FRBs) are being localised, we are learning that some fraction have persistent radio sources (PRSs). Such a discovery motivates an improvement in our unde…
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…
A Radio Flare in the Long-Lived Afterglow of the Distant Short GRB 210726A: Energy Injection or a Reverse Shock from Shell Collisions?
Genevieve Schroeder, Lauren Rhodes, Tanmoy Laskar +32
We present the discovery of the radio afterglow of the short -ray burst (GRB) 210726A, localized to a galaxy at a photometric redshift of . While radio observations c…
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…
Bursts from Space: MeerKAT - The first citizen science project dedicated to commensal radio transients
Alex Andersson, Chris Lintott, Rob Fender +40
The newest generation of radio telescopes are able to survey large areas with high sensitivity and cadence, producing data volumes that require new methods to better understand the…
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…
The Link Between Neutron Star X-ray Binaries and Spider Pulsars
Amy H. Knight, Adam Ingram, Jakob van den Eijnden +3
The discovery of transitional millisecond pulsars (tMSPs) provided conclusive proof that neutron star (NS) low-mass X-ray binaries (LMXBs) comprise part of the evolutionary pathway…
Day-timescale variability in the radio light curve of the Tidal Disruption Event AT2022cmc: confirmation of a highly relativistic outflow
L. Rhodes, J. S. Bright, R. Fender +9
Tidal disruption events (TDEs) are transient, multi-wavelength events in which a star is ripped apart by a supermassive black hole. Observations show that in a small fraction of TD…
The optical light curve of GRB 221009A: the afterglow and the emerging supernova
M. D. Fulton, S. J. Smartt, L. Rhodes +46
We present extensive optical photometry of the afterglow of GRB~221009A. Our data cover \,days from the time of \textit{Swift} and \textit{Fermi} GRB detections. Photom…
