Bright Lights Gamma-ray bursts (GRBs), bright flashes of gamma-ray light, are thought to be associated with the collapse of massive stars. GRB 130427A was detected on 27 April 2013, and it had the longest gamma-ray duration and one of the largest isotropic energy releases observed to date (see the Perspective by Fynbo). Ackermann et al. (p. 42, published online 21 November) report data obtained with the Fermi Gamma-Ray Space Telescope, which reveal a high-energy spectral component that cannot… Expand
Fermi-LAT Observations of the Gamma-Ray Burst GRB 130427A
TLDR
Temporal and spectral analyses of GRB 130427A challenge the widely accepted model that the nonthermal high-energy emission in the afterglow phase of GRBs is synchrotron emission radiated by electrons accelerated at an external shock. Expand
GRB 130427A: A Nearby Ordinary Monster
TLDR
A comprehensive multiwavelength view of GRB 130427A with Swift, the 2-meter Liverpool and Faulkes telescopes, and by other ground-based facilities is presented, highlighting the evolution of the burst emission from the prompt to the afterglow phase and suggesting that a common central engine is responsible for producing GRBs in both the contemporary and the early universe.

An Exceptionally Bright Gamma-Ray Burst
TLDR
A suite of satellites and ground-based observatories studied the emission from this burst at wavelengths ranging from radio waves over visible light to very high-energy γ-rays, providing an unprecedented opportunity to test and improve models of this spectacular class of cosmic explosions. Expand
GRB 120711A: an intense INTEGRAL burst with long-lasting soft γ-ray emission and a powerful optical flash
A long and intense γ-ray burst (GRB) was detected by INTEGRAL on 11 July 2012 with a duration of ∼115 s and fluence of 2.8 × 10 −4 erg cm −2 in the 20 keV−8 MeV energy range. GRB 120711A was at z ∼Expand
The 80 Ms follow-up of the X-ray afterglow of GRB 130427A challenges the standard forward shock model
