On The Lack of Time Dilation Signatures in Gamma-ray Burst Light Curves
Daniel Kocevski, Vahe Petrosian
We examine the effects of time dilation on the temporal profiles of gamma-ray burst (GRB) pulses. By using prescriptions for the shape and evolution of prompt gamma-ray spectra, we…
On The Origin Of High Energy Correlations in Gamma-ray Bursts
Daniel Kocevski
I investigate the origin of the observed correlation between a GRB's nuFnu spectral peak Epk and its isotropic equivalent energy Eiso through the use of a population synthesis code…
Fermi Large Area Telescope Second Source Catalog
LAT Collaboration
We present the second catalog of high-energy gamma-ray sources detected by the Large Area Telescope (LAT), the primary science instrument on the Fermi Gamma-ray Space Telescope (Fe…
An extremely luminous panchromatic outburst from the nucleus of a distant galaxy
A. J. Levan, N. R. Tanvir, S. B. Cenko +58
Variable X-ray and gamma-ray emission is characteristic of the most extreme physical processes in the Universe, and studying the sources of these energetic photons has been a major…
Detection of a spectral break in the extra hard component of GRB 090926A
Fermi-LAT, Fermi-GBM collaborations
We report on the observation of the bright, long gamma-ray burst, GRB 090926A, by the Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT) instruments on board the \Fermi\…
