Fermi-LAT Observations of the Gamma-ray Burst GRB 130427A
LAT collaboration, GBM collaboration
The observations of the exceptionally bright gamma-ray burst (GRB) 130427A by the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope provide constraints on the nature…
Spectroscopy of the short-hard GRB 130603B: The host galaxy and environment of a compact object merger
A. de Ugarte Postigo, C. C. Thoene, A. Rowlinson +40
Short duration gamma-ray bursts (SGRBs) are thought to be related to the violent merger of compact objects, such as neutron stars or black holes, which makes them promising sources…
Light from the Cosmic Frontier: Gamma-Ray Bursts
L. Amati, J. -L. Atteia, L. Balazs +41
Gamma-Ray Bursts (GRBs) are the most powerful cosmic explosions since the Big Bang, and thus act as signposts throughout the distant Universe. Over the last 2 decades, these ultra-…
The Burst Cluster: Dark Matter in a Cluster Merger Associated with the Short Gamma Ray Burst, GRB 050509B
Hakon Dahle, Craig L. Sarazin, Laura A. Lopez +11
We have identified a merging galaxy cluster with evidence of two distinct sub-clusters. The X-ray and optical data suggest that the subclusters are moving away from each other afte…
The First Fermi LAT Gamma-Ray Burst Catalog
LAT Collaboration
In three years of observations since the beginning of nominal science operations in August 2008, the Large Area Telescope (LAT) on board the Fermi Gamma Ray Space Telescope has obs…
Applying an accurate spherical model to gamma-ray burst afterglow observations
Konstantinos Leventis, Alexander J. van der Horst, Hendrik J. van Eerten +1
We present results of model fits to afterglow data sets of GRB970508, GRB980703 and GRB070125, characterized by long and broadband coverage. The model assumes synchrotron radiation…
