Evidence of an upper ionospheric electric field perturbation correlated with a gamma ray burst [PDF]

Nature Communications, 2023
Earth’s atmosphere, whose ionization stability plays a fundamental role for the evolution and endurance of life, is exposed to the effect of cosmic explosions producing high energy Gamma-ray-bursts.

A peculiar low-luminosity short gamma-ray burst from a double neutron star merger progenitor [PDF]

Nature Communications, 2018
A short-duration gamma-ray burst was detected along with a double neutron start merger gravitational wave by LIGO-Virgo on August 17th 2017. Here, the authors show that the fluence and spectral peak energy of this event fall into the lower portion of the

The Structure of Gamma Ray Burst Jets

Galaxies, 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.

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

Galaxies, 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

Universe, 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

Universe, 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 ...

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

The 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
