The most distant optically polarised GRB afterglow: GRB 240419A at z = 5.178

R. Brivio, S. Covino, M. Ferro +31

Gamma-ray bursts (GRBs) are extremely bright phenomena powered by relativistic jets arising from explosive events at cosmological distances. The nature of the jet and the configura…

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…

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…

JWST reveals a supernova following a gamma-ray burst at z 7.3

A. J. Levan, B. Schneider, E. Le Floc'h +50

The majority of energetic long-duration gamma-ray bursts (GRBs) are thought to arise from the collapse of massive stars, making them powerful tracers of star formation across cosmi…

The infrared counterpart and proper motion of magnetar SGR0501+4516

A. A. Chrimes, A. J. Levan, J. D. Lyman +19

Soft gamma repeaters (SGRs) are highly magnetised neutron stars (magnetars) notable for their gamma-ray and X-ray outbursts. In this paper, we use near-infrared (NIR) imaging of SG…

Constraints on optical and near-infrared variability in the localisation of the long-period radio transient GLEAM-X J1627-52

J. D. Lyman, V. S. Dhillon, S. Kamann +5

GLEAM-X J1627-52 was discovered as a periodic (~18 min) radio signal over a duration of three months in 2018. It is an enigmatic example of a growing population of 'long-period rad…
