The Structure of Gamma Ray Burst Jets

open access: yesGalaxies, 2022
Due to relativistic bulk motion, the structure and orientation of gamma-ray burst (GRB) jets have a fundamental role in determining how they appear.

The Fourth Fermi-GBM Gamma-Ray Burst Catalog: A Decade of Data [PDF]

open access: yesAstrophysical Journal, 2020
We present the fourth in a series of catalogs of gamma-ray bursts (GRBs) observed with Fermi’s Gamma-ray Burst Monitor (Fermi-GBM). It extends the six year catalog by four more years, now covering the 10 year time period from trigger enabling on 2008 ...

A Roadmap to Gamma-Ray Bursts: New Developments and Applications to Cosmology

open access: yesGalaxies, 2021
Gamma-ray bursts are the most powerful explosions in the universe and are mainly placed at very large redshifts, up to z≃9. In this short review, we first discuss gamma-ray burst classification and morphological properties.

Critical Tests of Leading Gamma Ray Burst Theories

open access: yesUniverse, 2022
It has been observationally established that supernovae (SNe) of Type Ic produce long duration gamma-ray bursts (GRBs) and that neutron star mergers generate short hard GRBs.

Swift/UVOT: 18 Years of Long GRB Discoveries and Advances

open access: yesUniverse, 2023
The Neil Gehrels Swift Observatory (Swift) has been in operation for 18 years. The Ultra-Violet/Optical Telescope (UVOT) onboard Swift was designed to capture the earliest optical/UV emission from gamma-ray bursts (GRBs), spanning the first few minutes ...

The Swift Gamma-Ray Burst Mission [PDF]

open access: yes, 2004
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 for transient astronomy and pioneers the way for future rapid-reaction and

GRB 221009A: The BOAT

open access: yesThe Astrophysical Journal Letters, 2023
GRB 221009A has been referred to as the brightest of all time (BOAT). We investigate the veracity of this statement by comparing it with a half century of prompt gamma-ray burst observations.

Deep Multimessenger Search for Compact Binary Mergers in LIGO, Virgo, and Fermi/GBM Data from 2016–2017

open access: yesThe Astrophysical Journal, 2023
GW170817–GRB 170817A provided the first observation of gravitational waves from a neutron star merger with associated transient counterparts across the entire electromagnetic spectrum. This discovery demonstrated the long-hypothesized association between

An Ordinary Short Gamma-Ray Burst with Extraordinary Implications: Fermi-GBM Detection of GRB 170817A [PDF]

open access: yes, 2017
On 2017 August 17 at 12:41:06 UTC the Fermi Gamma-ray Burst Monitor (GBM) detected and triggered on the short gamma-ray burst (GRB) 170817A. Approximately 1.7 s prior to this GRB, the Laser Interferometer Gravitational-wave Observatory triggered on a ...

Spectra and Light Curves of Gamma-Ray Burst Afterglows [PDF]

open access: yes, 1997
The recently discovered gamma-ray burst afterglow is believed to be described reasonably well by synchrotron emission from a decelerating relativistic shell that collides with an external medium. To compare theoretical models with afterglow observations,
