TL;DR: Observations suggest a sudden accretion event onto a central MBH of mass about 106 to 107 solar masses, which leads to a natural analogy of Sw 1644+57 to a temporary smaller-scale blazar.
Journal ArticleDOI

TL;DR: In this paper, the authors presented systematic spectral analyses of gamma-ray bursts (GRBs) detected by the Fermi Gamma-Ray Burst Monitor (GBM) during its first two years of operation.
Journal ArticleDOI
Gamma-Ray Burst Afterglow Broadband Fitting Based Directly on Hydrodynamics Simulations
TL;DR: In this paper, the authors present a powerful new tool for fitting broadband gamma-ray burst afterglow data, which can be used to determine the burst explosion parameters and the synchrotron radiation parameters.
