Unveiling the nature of the Einstein Probe transient EP 241021a

J. Quirola-Vásquez, P. G. Jonker, A. J. Levan +23

We present a multi-wavelength analysis of the fast X-ray transient EP 241021a, discovered by the Wide-field X-ray Telescope aboard the \emph{Einstein Probe} satellite on 2024 Octob…

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…

JWST Spectroscopy of GRB 250702B: An Extremely Rare and Exceptionally Energetic Burst in a Dusty, Massive Galaxy at

Benjamin P. Gompertz, Andrew J. Levan, Tanmoy Laskar +25

We present follow-up observations of the day-long, repeating GRB 250702B with the Near Infrared Spectrograph (NIRSpec) on board the James Webb Space Telescope (JWST). Through the i…

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…

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…

GRB 241105A: A test case for GRB classification and rapid r-process nucleosynthesis channels

Dimple, B. P. Gompertz, A. J. Levan +85

Gamma-ray bursts (GRBs) offer a powerful window to probe the progenitor systems responsible for the formation of heavy elements through the rapid neutron capture (r-) process, than…

A large, chemically enriched, neutral gas reservoir in a galaxy at z = 6.782

A. Saccardi, S. D. Vergani, L. Izzo +23

The chemical characterization of galaxies in the first billion years after the Big Bang is one of the central goals of current astrophysics. Optical/near-infrared spectroscopy of l…

EP 250108a/SN 2025kg: Observations of the most nearby Broad-Line Type Ic Supernova following an Einstein Probe Fast X-ray Transient

J. C. Rastinejad, A. J. Levan, P. G. Jonker +66

With a small sample of fast X-ray transients (FXTs) with multi-wavelength counterparts discovered to date, the progenitors of FXTs and their connections to gamma-ray bursts (GRBs)…
