Low-frequency-selected Fast Radio Burst Host Galaxy Candidates

Yu-Zhu Sun, Rhaana L. C. Starling, Rob A. J. Eyles-Ferris +3

We present a pilot study on the host galaxy environments of CHIME/FRBs by cross-matching baseband-localised events with the LOFAR Two-metre Sky Survey Data Release 2 (LoTSS DR2) at…

First Results from the PanRadio Gamma-Ray Burst Collaboration: The 400-day Afterglow of GRB 230815A

James K. Leung, Gemma E. Anderson, Alexander J. van der Horst +26

We introduce the PanRadio Gamma-ray Burst (GRB) program carried out on the Australia Telescope Compact Array: a systematic, multi-year, radio survey of all southern $\textit{Swift}…

Discovery and Analysis of Afterglows from Poorly Localised GRBs with the Gravitational-wave Optical Transient Observer (GOTO) All-sky Survey

Amit Kumar, B. P. Gompertz, B. Schneider +86

Gamma-ray bursts (GRBs), particularly those detected by wide-field instruments such as the Fermi/GBM, pose a challenge for optical follow-up due to their large initial localisation…

Sporadic radio pulses from a white dwarf binary at the orbital period

I. de Ruiter, K. M. Rajwade, C. G. Bassa +14

Recent observations have revealed rare, previously unknown flashes of cosmic radio waves lasting from milliseconds to minutes, and with periodicity of minutes to an hour. These tra…

A LOFAR search for coherent radio emission accompanying prompt engine activity in gamma-ray bursts

A. Hennessy, R. L. C. Starling, A. Rowlinson +7

Relativistic jets generated in gamma-ray bursts (GRBs) produce luminous transient events, yet the fundamentals of jet composition and radiation mechanisms remain unclear. One means…

The radio flare and multi-wavelength afterglow of the short GRB 231117A: energy injection from a violent shell collision

G. E. Anderson, G. P. Lamb, B. P. Gompertz +64

We present the early radio detection and multi-wavelength modeling of the short gamma-ray burst (GRB) 231117A at redshift . The Australia Telescope Compact Array automatic…
