Photometric and Spectroscopic Observations of GRB 190106A: Emission from Reverse and Forward Shocks with Late-time Energy Injection

Zhu, Zi-Pei Xu, Dong Fynbo, Johan P.U

Early optical observations of gamma-ray bursts can significantly contribute to the study of the central engine and physical processes therein. However, of the thousands observed so far, still only a few have data at optical wavelengths in the first minutes after the onset of the prompt emission. Here we report on GRB 190106A, whose afterglow...

Optical and Near-infrared Observations of the Distant but Bright 'New Year's Burst' GRB 220101A

Zhu, Zi-Pei Lei, Wei-Hua Malesani, Daniele B

High-redshift gamma-ray bursts (GRBs) provide a powerful tool to probe the early universe, but still for relatively few do we have good observations of the afterglow. We here report the optical and near-infrared observations of the afterglow of a relatively high-redshift event, GRB 220101A, triggered on New Year's Day of 2022. With the optical...
