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… 

The Bright Optical Flash and Afterglow from the Gamma-Ray Burst GRB 130427A

TLDR
The link between optical afterglow and >100-MeV emission suggests that nearby early peaked afterglows will be the best candidates for studying gamma-ray emission at energies ranging from gigaelectron volts to teraelectrons volts.

The First Pulse of the Extremely Bright GRB 130427A: A Test Lab for Synchrotron Shocks

TLDR
Multiwavelength data from an extremely bright stellar explosion provide details of the physics of these violent events, and suggests that existing models cannot explain all the observed spectral and temporal behaviors simultaneously.

MODELING THE EARLY MULTIWAVELENGTH EMISSION IN GRB 130427A

One of the most powerful gamma-ray bursts, GRB 130427A was swiftly detected from GeV γ-rays to optical wavelengths. In the GeV band, the Large Area Telescope (LAT) on board the Fermi Gamma-Ray Space

CONSTRAINTS ON VERY HIGH ENERGY EMISSION FROM GRB 130427A

Prompt emission from the very fluent and nearby (z = 0.34) gamma-ray burst GRB 130427A was detected by several orbiting telescopes and by ground-based, wide-field-of-view optical transient monitors.

The first limits on the prompt emission from the long gamma-ray burst (GRB) 130427A in the >100 GeV energy band are reported. GRB 130427A was the most powerful burst ever detected with a redshift z ≲

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.

Time delays between Fermi-LAT and GBM light curves of gamma-ray bursts

Aims. Most gamma-ray bursts (GRBs) detected by the Fermi Gamma-ray Space Telescope exhibit a delay of up to about 10 seconds between the trigger time of the hard X-ray signal as measured by the Fermi

A Decade of Gamma-Ray Bursts Observed by Fermi-LAT: The Second GRB Catalog

The Large Area Telescope (LAT) aboard the Fermi spacecraft routinely observes high-energy emission from gamma-ray bursts (GRBs). Here we present the second catalog of LAT-detected GRBs, covering the

GRB 110721A was detected by the Gamma-ray Burst Monitor and the Large Area Telescope (LAT) on board the Fermi satellite and the Gamma-ray Burst Polarimeter on board the IKAROS solar mission. Previous

Analysis and Modeling of the Multi-wavelength Observations of the Luminous GRB 190114C

Very-high-energy (VHE; ≥ 10 GeV) photons are expected from the nearest and brightest gamma-ray bursts (GRBs). VHE photons, at energies higher than 300 GeV, were recently reported by the MAGIC

Detection of a γ-ray burst of very long duration and very high energy

ALTHOUGH γ-ray bursts (GRBs) have been known for more than 20 years, their origin remains mysterious1. Suggestions have ranged from nearby colliding comets2 to merging neutron stars at cosmological

The Gamma-Ray Burst Monitor (GBM) will significantly augment the science return from the Fermi Observatory in the study of gamma-ray bursts (GRBs). The primary objective of GBM is to extend the

On the generation of high-energy photons detected by the Fermi Satellite from gamma-ray bursts
