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…

A Search for Low-frequency Radio Pulses from Long Gamma-ray Bursts with the Murchison Widefield Array

Fan Xu, G. E. Anderson, Jun Tian +10

It has been proposed that coherent radio emission could be emitted during or shortly following a gamma-ray burst (GRB). Here we present a low-frequency ( MHz) search for r…

Commensal Transient Searches with MeerKAT in Gamma-Ray Burst and Supernova Fields

S. I. Chastain, A. J. van der Horst, A. Horesh +6

The sensitivity and field of view of the MeerKAT radio telescope provides excellent opportunities for commensal transient searches. We carry out a commensal transient search in sup…

The early radio afterglow of short GRB 230217A

G. E. Anderson, G. Schroeder, A. J. van der Horst +9

We present the radio afterglow of short gamma-ray burst (GRB) 230217A, which was detected less than 1 day after the gamma-ray prompt emission with the Australia Telescope Compact A…

Rocking the BOAT: the ups and downs of the long-term radio light curve for GRB 221009A

L. Rhodes, A. J. van der Horst, J. S. Bright +24

We present radio observations of the long-duration gamma-ray burst (GRB) 221009A which has become known to the community as the Brightest Of All Time or the BOAT. Our observations…
