The "amplitude" parameter of Gamma-Ray Bursts and its implications for GRB classification
Hou-Jun Lü, Bing Zhang, En-Wei Liang +2
Traditionally gamma-ray bursts (GRBs) are classified in the -hardness ratio two-dimensional plane into long/soft and short/hard GRBs. In this paper, we suggest to add the "…
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…
Radial Angular Momentum Transfer and Magnetic Barrier for Short-Type Gamma-Ray Burst Central Engine Activity
Tong Liu, En-Wei Liang, Wei-Min Gu +5
Soft extended emission (EE) following initial hard spikes up to 100 seconds was observed with {\em Swift}/BAT for about half of short-type gamma-ray bursts (SGRBs). This challenges…

Multi-wavelength observations of blazar AO 0235+164 in the 2008-2009 flaring state
M. Ackermann, M. Ajello, J. Ballet +208
The blazar AO 0235+164 (z = 0.94) has been one of the most active objects observed by Fermi Large Area Telescope (LAT) since its launch in Summer 2008. In addition to the continuou…
Gamma-ray observations of the Orion Molecular Clouds with the Fermi Large Area Telescope

In early October 2008, the Soft Gamma Repeater SGRJ1550 - 5418 (1E 1547.0 - 5408, AXJ155052 - 5418, PSR J1550 - 5418) became active, emitting a series of bursts which triggered the…
GeV Observations of Star-forming Galaxies with \textit{Fermi} LAT
Fermi LAT Collaboration, M. Ackermann, M. Ajello +127
Recent detections of the starburst galaxies M82 and NGC 253 by gamma-ray telescopes suggest that galaxies rapidly forming massive stars are more luminous at gamma-ray energies comp…
Cosmic ray transport and anisotropies
P. L. Biermann, J. K. Becker, E. -S. Seo +1
We show that the large-scale cosmic ray anisotropy at ~10 TeV can be explained by a modified Compton-Getting effect in the magnetized flow field of old supernova remnants. This app…
Fermi LAT Search for Dark Matter in Gamma-ray Lines and the Inclusive Photon Spectrum
LAT Collaboration, M. Ackermann, M. Ajello +117
Dark matter particle annihilation or decay can produce monochromatic gamma-ray lines and contribute to the diffuse gamma-ray background. Flux upper limits are presented for gamma-r…
