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…

Time-domain astrophysics continues to grow rapidly, with the inception of new surveys drastically increasing data volumes. Democratised, distributed approaches to training sets for…
Rapid Response Mode observations of GRB 160203A: Looking for fine-structure line variability at z=3.52
G. Pugliese, A. Saccardi, V. D Elia +26
Gamma-ray bursts are the most energetic known explosions. Despite fading rapidly, they allow to measure redshift and important properties of their host-galaxies. We report the phot…
Varying linear polarisation in the dust-free GRB 210610B
J. F. Agüí Fernández, A. de Ugarte Postigo, C. C. Thöne +19
Long gamma ray bursts (GRBs) are produced by the collapse of some very massive stars, which emit ultra-relativistic jets. When the jets collide with the interstellar medium they de…
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…
Comparing emission- and absorption-based gas-phase metallicities in GRB host galaxies at using JWST
P. Schady, R. M. Yates, L. Christensen +34
Much of what is known of the chemical composition of the universe is based on emission line spectra from star forming galaxies. Emission-based inferences are, nevertheless, model-d…

A. Hennessy, R. L. C. Starling, A. Rowlinson +14
The composition of relativistic gamma-ray burst (GRB) jets and their emission mechanisms are still debated, and they could be matter or magnetically dominated. One way to distingui…
