We provide a comprehensive review of major developments in our understanding of gamma-
ray bursts, with particular focus on the discoveries made within the last fifteen years when …

Abstract 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 …

The number of gamma-ray bursts (GRBs) detected at high energies (∼ 0. 1− 1 0 0 GeV) has
seen a rapid increase over the last decade, thanks to observations from the Fermi-Large …

In three years of observations since the beginning of nominal science operations in 2008
August, the Large Area Telescope (LAT) on board the Fermi Gamma-Ray Space Telescope …

Long-duration γ-ray bursts (GRBs) originate from ultra-relativistic jets launched from the
collapsing cores of dying massive stars. They are characterized by an initial phase of bright …

Newly formed black holes of stellar mass launch collimated outflows (jets) of ionized matter
that approach the speed of light. These outflows power prompt, brief and intense flashes of γ …

We consider a sample of 10 gamma-ray bursts with long-lasting (≳ 102 s) emission detected
by Fermi/Large Area Telescope and for which X-ray data around 1 d are also available. We …

Gamma-ray bursts (GRBs) are one of the most promising transient events for studying
multiwavelength observations in extreme conditions. Observation of GeV photons from …

GRB 190114C, a long and luminous burst, was detected by several satellites and ground-
based telescopes from radio wavelengths to GeV gamma-rays. In the GeV gamma-rays, the …
