Confronting GRB prompt emission with a model for subphotospheric dissipation
Björn Ahlgren, Josefin Larsson, Tanja Nymark +2
The origin of the prompt emission in gamma-ray bursts (GRBs) is still an unsolved problem and several different mechanisms have been suggested. Here we fit Fermi GRB data with a ph…
The First Pulse of the Extremely Bright GRB 130427A: A Test Lab for Synchrotron Shocks
R. Preece, J. Michael Burgess, A. von Kienlin +156
Gamma-ray burst (GRB) 130427A is one of the most energetic GRBs ever observed. The initial pulse up to 2.5 s is possibly the brightest well-isolated pulse observed to date. A fine…
Variable jet properties in GRB110721A: Time resolved observations of the jet photosphere
Shabnam Iyyani, Felix Ryde, Magnus Axelsson +8
{\it Fermi Gamma-ray Space Telescope} observations of GRB110721A have revealed two emission components from the relativistic jet: emission from the photosphere, peaking at $\sim 10…
Multiwavelength observations of GRB 110731A: GeV emission from onset to afterglow
LAT Collaboration, GBM Collaboration, Swift Collaboration +2
We report on the multiwavelength observations of the bright, long gamma-ray burst \GRB, by the \Fermi and \Swift observatories, and by the MOA and GROND optical telescopes. The ana…
GRB110721A: An extreme peak energy and signatures of the photosphere
The Fermi LAT Collaboration, the GBM Collaboration, A. Pe'er
GRB110721A was observed by the Fermi Gamma-ray Space Telescope using its two instruments the Large Area Telescope (LAT) and the Gamma-ray Burst Monitor (GBM). The burst consisted o…
Constraining the High-Energy Emission from Gamma-ray Bursts with Fermi
LAT Collaboration, GBM Collaboration
We examine 288 GRBs detected by the Fermi Gamma-ray Space Telescope's Gamma-ray Burst Monitor (GBM) that fell within the field-of-view of Fermi's Large Area Telescope (LAT) during…
