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…

EP250207b is not a collapsar fast X-ray transient. Is it due to a compact object merger?

P. G. Jonker, A. J. Levan, Xing Liu +41

Fast X-ray Transients (FXTs) are short-lived extra-galactic X-ray sources. Recent progress through multi-wavelength follow-up of Einstein Probe discovered FXTs has shown that sever…

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…

SVOM GRB 250314A at z 7.3: an exploding star in the era of reionization

B. Cordier, J. Y. Wei, N. R. Tanvir +103

Most long Gamma-ray bursts originate from a rare type of massive stellar explosion. Their afterglows, while rapidly fading, can be initially extremely luminous at optical/near-infr…

The kangaroo's first hop: the early fast cooling phase of EP250108a/SN 2025kg

Rob A. J. Eyles-Ferris, Peter G. Jonker, Andrew J. Levan +52

Fast X-ray transients (FXTs) are a rare and poorly understood population of events. Previously difficult to detect in real time, the launch of the Einstein Probe with its wide fiel…
