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…
