The physics of gamma-ray bursts

T Piran - Reviews of Modern Physics, 2004 - APS
Gamma-ray bursts (GRB's), short and intense pulses of low-energy γ rays, have fascinated
astronomers and astrophysicists since their unexpected discovery in the late sixties. During …

The supernova–gamma-ray burst connection

SE Woosley, JS Bloom - Annu. Rev. Astron. Astrophys., 2006 - annualreviews.org
Observations show that at least some gamma-ray bursts (GRBs) happen simultaneously
with core-collapse supernovae (SNe), thus linking by a common thread nature's two …

Heavy-element production in a compact object merger observed by JWST

AJ Levan, BP Gompertz, OS Salafia, M Bulla, E Burns… - Nature, 2024 - nature.com
The mergers of binary compact objects such as neutron stars and black holes are of central
interest to several areas of astrophysics, including as the progenitors of gamma-ray bursts …

A lanthanide-rich kilonova in the aftermath of a long gamma-ray burst

YH Yang, E Troja, B O'Connor, CL Fryer, M Im… - Nature, 2024 - nature.com
Observationally, kilonovae are astrophysical transients powered by the radioactive decay of
nuclei heavier than iron, thought to be synthesized in the merger of two compact objects …

Collapsars: Gamma-ray bursts and explosions in “failed supernovae”

AI MacFadyen, SE Woosley - The Astrophysical Journal, 1999 - iopscience.iop.org
Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued
evolution of rotating helium stars, M α≳ 10 M⊙, in which iron-core collapse does not …

Gamma-ray bursts

P Meszaros - Reports on Progress in Physics, 2006 - iopscience.iop.org
Gamma-ray bursts are the most luminous explosions in the Universe, and their origin and
mechanism are the focus of intense research and debate. More than three decades after …

Short-hard gamma-ray bursts

E Nakar - Physics Reports, 2007 - Elsevier
Two types of gamma-ray bursts (GRBs) are observed: short-duration hard spectrum GRBs
and long-duration soft spectrum GRBs. For many years long GRBs were the focus of intense …

Wind interaction models for gamma-ray burst afterglows: the case for two types of progenitors

RA Chevalier, ZY Li - The Astrophysical Journal, 2000 - iopscience.iop.org
Beginning with the γ-ray bursts GRB 970228 and GRB 970508, a standard model for the
interpretation of gamma-ray burst (GRB) afterglows emerged involving synchrotron emission …

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 …

Formation rates of black hole accretion disk gamma-ray bursts

CL Fryer, SE Woosley, DH Hartmann - The Astrophysical Journal, 1999 - iopscience.iop.org
The cosmological origin of at least an appreciable fraction of classical gamma-ray bursts
(GRBs) is now supported by redshift measurements for a half-dozen faint host galaxies. Still …
