Rapid Response Mode observations of GRB 160203A: Looking for fine-structure line variability at z=3.52

Pugliese, G Saccardi, A Elia, V.D

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 photometric and spectroscopic study of GRB 160203A and its host-galaxy. Fine-structure absorption lines, detected in the afterglow at different epochs, allow us to...

The brightest GRB ever detected: GRB 221009A as a highly luminous event at z = 0.151

Malesani, D.B Levan, A.J Izzo, L

Context: The extreme luminosity of gamma-ray bursts (GRBs) makes them powerful beacons for studies of the distant Universe. The most luminous bursts are typically detected at moderate/high redshift, where the volume for seeing such rare events is maximized and the star-formation activity is greater than at z = 0. For distant events, not all...
