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…

First joint absorption and T $_{e}$ -based metallicity measured in a GRB host galaxy at $z = 4.28$ using JWST/NIRSpec

Anne Inkenhaag, Patricia Schady, Phil Wiseman +20

We present the first gamma-ray burst (GRB) host galaxy with a measured absorption line and electron temperature (T $_{e}$ ) based metallicity, using the temperature sensitive [OIII]$Î»…

First IFU observations of two GRB host galaxies at cosmic noon with JWST/NIRSpec

B. TopÃ§u, P. Schady, S. Wuyts +16

Long gamma-ray bursts (GRBs) serve as powerful probes of distant galaxies. Their luminous afterglow pinpoints galaxies independent of luminosity, in contrast to most flux-limited s…
