Unveiling the engines of fast radio bursts, superluminous supernovae, and gamma-ray bursts [PDF]

Monthly notices of the Royal Astronomical Society, 2018
Young, rapidly spinning magnetars are invoked as central engines behind a diverse set of transient astrophysical phenomena, including gamma-ray bursts (GRB), super-luminous supernovae (SLSNe), fast radio bursts (FRB), and binary neutron star (NS) mergers.

Short Gamma Ray Bursts as possible electromagnetic counterpart of coalescing binary systems [PDF]

, 2010
Coalescing binary systems, consisting of two collapsed objects, are among the most promising sources of high frequency gravitational waves signals detectable, in principle, by ground-based interferometers.

Collapsars: Gamma-Ray Bursts and Explosions in “Failed Supernovae” [PDF]

, 1998
Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued evolution of rotating helium stars, Mα ≳ 10 M☉, in which iron-core collapse does not produce a successful outgoing shock but instead forms a black hole of 2-3 M☉. The model

Very high-energy gamma-ray emission beyond 10 TeV from GRB 221009A [PDF]

Science Advances, 2023
The highest-energy gamma-rays from gamma-ray bursts (GRBs) have important implications for their radiation mechanism. Here we report the detection of gamma-rays up to 13 teraelectronvolts from the brightest GRB 221009A by the Large High Altitude Air ...

Gamma-ray bursts [PDF]

Reports on Progress in Physics, 2006
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 their discovery, and after pioneering breakthroughs from space and ground experiments, their study is entering a new phase with the recently launched Swift satellite. The interplay

GRB Redshift determination in the X-ray band [PDF]

, 1999
If gamma-ray bursts originate in dense stellar forming regions, the interstellar material can imprint detectable absorption features on the observed X-ray spectrum.

Off-axis Prompt X-Ray Transients from the Cocoon of Short Gamma-Ray Bursts [PDF]

We present the results of numerical simulations of the prompt emission of short-duration gamma-ray bursts. We consider emission from the relativistic jet, the mildly relativistic cocoon, and the non-relativistic shocked ambient material. We find that the

The Diversity of Kilonova Emission in Short Gamma-Ray Bursts [PDF]

Astrophysical Journal, 2017
The historic first joint detection of both gravitational-wave and electromagnetic emission from a binary neutron star merger cemented the association between short gamma-ray bursts (SGRBs) and compact object mergers, as well as providing a well-sampled ...

Gamma-Ray Burst Progenitors [PDF]

Space Science Reviews, 2016
We review our current understanding of the progenitors of both long and short duration gamma-ray bursts (GRBs). Constraints can be derived from multiple directions, and we use three distinct strands; i) direct observations of GRBs and their host galaxies, ii) parameters derived from modeling, both via population synthesis and direct numerical ...
