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…

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…

Revisiting the Intergalactic Medium Around GRB 130606A and Constraints on the Epoch of Reionization

H. M. Fausey, A. J. van der Horst, N. R. Tanvir +4

Gamma-ray bursts (GRBs) are excellent probes of the high-redshift Universe due to their high luminosities and the relatively simple intrinsic spectra of their afterglows. They can…

Neutral Fraction of Hydrogen in the Intergalactic Medium Surrounding High-Redshift Gamma-Ray Burst 210905A

H. M. Fausey, S. Vejlgaard, A. J. van der Horst +22

The Epoch of Reionization (EoR) is a key period of cosmological history in which the intergalactic medium (IGM) underwent a major phase change from being neutral to almost complete…
