The physics of gamma-ray bursts & relativistic jets

P Kumar, B Zhang - Physics Reports, 2015 - Elsevier
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 …

Short-duration gamma-ray bursts

E Berger - Annual review of Astronomy and Astrophysics, 2014 - annualreviews.org
Gamma-ray bursts (GRBs) display a bimodal duration distribution with a separation between
the short-and long-duration bursts at about 2 s. The progenitors of long GRBs have been …

Gigaelectronvolt emission from a compact binary merger

A Mei, B Banerjee, G Oganesyan, OS Salafia… - Nature, 2022 - nature.com
An energetic γ-ray burst (GRB), GRB 211211A, was observed on 11 December 2021,.
Despite its long duration, typically associated with bursts produced by the collapse of …

The Swift gamma-ray burst mission

N Gehrels, G Chincarini, PE Giommi… - The Astrophysical …, 2004 - iopscience.iop.org
The Swift mission, scheduled for launch in 2004, is a multiwavelength observatory for
gamma-ray burst (GRB) astronomy. It is a first-of-its-kind autonomous rapid-slewing satellite …

Methods and results of an automatic analysis of a complete sample of Swift-XRT observations of GRBs

PA Evans, AP Beardmore, KL Page… - Monthly Notices of …, 2009 - academic.oup.com
We present a homogeneous X-ray analysis of all 318 gamma-ray bursts detected by the X-
ray telescope (XRT) on the Swift satellite up to 2008 July 23; this represents the largest …

The internal-collision-induced magnetic reconnection and turbulence (ICMART) model of gamma-ray bursts

B Zhang, H Yan - The Astrophysical Journal, 2010 - iopscience.iop.org
The recent Fermi observation of GRB 080916C shows that the bright photosphere emission
associated with a putative fireball is missing, which suggests that the central engine likely …

The protomagnetar model for gamma-ray bursts

BD Metzger, D Giannios, TA Thompson… - Monthly Notices of …, 2011 - academic.oup.com
Long duration gamma-ray bursts (GRBs) originate from the core collapse of massive stars,
but the identity of the central engine remains elusive. Previous work has shown that rapidly …

A long-lived neutron star merger remnant in GW170817: constraints and clues from X-ray observations

L Piro, E Troja, B Zhang, G Ryan… - Monthly Notices of …, 2019 - academic.oup.com
Multimessenger observations of GW170817 have not conclusively established whether the
merger remnant is a black hole (BH) or a neutron star (NS). We show that a long-lived …

Gamma-Ray Bursts in the Swift Era

N Gehrels, E Ramirez-Ruiz… - Annual Review of …, 2009 - annualreviews.org
With its rapid-response capability and multiwavelength complement of instruments, the Swift
satellite has transformed our physical understanding of γ-ray bursts (GRBs). Providing high …

Discerning the physical origins of cosmological gamma-ray bursts based on multiple observational criteria: the cases of z= 6.7 GRB 080913, z= 8.2 GRB 090423, and …

B Zhang, BB Zhang, FJ Virgili, EW Liang… - The Astrophysical …, 2009 - iopscience.iop.org
The two high-redshift gamma-ray bursts, GRB 080913 at z= 6.7 and GRB 090423 at z= 8.2,
recently detected by Swift appear as intrinsically short, hard GRBs. They could have been …
