Recent observations have confirmed that Gamma-Ray Burst (GRB) afterglows produce Very High-Energy radiation (VHE, E>
100GeV). This highly anticipated discovery opens new scenarios in the interpretation of GRBs and in their role as probes of Ex

A Comparison between Radio Loud and Quiet Gamma-Ray Bursts, and Evidence for a Potential Correlation between Intrinsic Duration and Redshift in the Radio Loud Population

Autor: Asaf Pe'er, Andrew S. Fruchter, Maria Giovanna Dainotti, Nicole M. Lloyd-Ronning, B. P. Gompertz

Publikováno v: The Astrophysical Journal

We extend our study of energetic radio loud and quiet gamma-ray bursts (GRBs), suggesting these GRBs potentially come from two separate progenitor systems. We expand the sample from our previous paper (Lloyd-Ronning & Fryer, 2017) and find our result

Publisher's version (útgefin grein)
We present here a survey of high-ionization absorption lines in the afterglow spectra of long-duration gamma-ray bursts (GRBs) obtained with the VLT/X-shooter spectrograph. Our main goal is to investigate the

14 pages, 8 figures. The paper has been accepted by Research in Astronomy and Astrophysics (RAA)
Rapid response and short time latency are very important for Time Domain Astronomy, such as the observations of Gamma-ray Bursts (GRBs) and electrom

The physical origin of the >0.1 GeV emission detected from Gamma-Ray Bursts (GRBs) by the Fermi satellite has not yet been completely understood. In this work we consider the GeV light curves of ten GRBs with measured redshift detected by the Fermi-L
