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…
Evidence for a Photospheric Component in the Prompt Emission of the Short GRB120323A and its Effects on the GRB Hardness-Luminosity Relation
S. Guiriec, F. Daigne, R. Hascoët +12
The short GRB 120323A had the highest flux ever detected with the Fermi/GBM. Here we study its remarkable spectral properties and their evolution using two spectral models: (i) a s…
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…
The Fermi GBM Gamma-Ray Burst Spectral Catalog: The First Two Years
Adam Goldstein, J. Michael Burgess, Robert D. Preece +25
We present systematic spectral analyses of GRBs detected by the Fermi Gamma-Ray Burst Monitor (GBM) during its first two years of operation. This catalog contains two types of spec…
