Gamma-Ray Burst Prompt Emission [PDF]

, 2014
The origin of gamma-ray burst (GRB) prompt emission, bursts of gamma-rays lasting from shorter than one second to thousands of seconds, remains not fully understood after more than 40 years of observations. The uncertainties lie in several open questions

A tera–electron volt afterglow from a narrow jet in an extremely bright gamma-ray burst [PDF]

Science, 2023
Some gamma-ray bursts (GRBs) have a tera–electron volt (TeV) afterglow, but the early onset of this has not been observed. We report observations with the Large High Altitude Air Shower Observatory (LHAASO) of the bright GRB 221009A, which ...

A long-duration gamma-ray burst with a peculiar origin [PDF]

Nature, 2022
It is generally believed that long-duration gamma-ray bursts (GRBs) are associated with massive star core collapse1, whereas short-duration GRBs are associated with mergers of compact star binaries2.

Neutrinos from the Brightest Gamma-Ray Burst? [PDF]

Astrophysical Journal Letters, 2022
We discuss implications that can be obtained by searches for neutrinos from the brightest gamma-ray burst (GRB), GRB 221009A. We derive constraints on GRB model parameters such as the cosmic-ray loading factor and dissipation radius, taking into account ...

Evidence for an intermediate-mass black hole from a gravitationally lensed gamma-ray burst [PDF]

Nature Astronomy, 2021
If gamma-ray bursts are at cosmological distances, they must be gravitationally lensed occasionally1,2. The detection of lensed images with millisecond-to-second time delays provides evidence for intermediate-mass black holes, a population that has been ...

Gamma-Ray Bursts [PDF]

Science, 2012
Stellar Explosions Stars that are born with masses greater than eight times that of the Sun end their lives in luminous explosions known as supernovae. Over the past decade, access to improved sky surveys has revealed rare types of supernovae that are much more luminous than any of those that were known before.

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.

GAMMA-RAY BURSTS [PDF]

Particles, Strings and Cosmology (PASCOS 99), 2000
Ultra-high-energy, >10^19 eV, cosmic-ray and high energy, ~10^14 eV, neutrino production in GRBs is discussed in the light of recent GRB and cosmic-ray observations. Emphasis is put on model predictions that can be tested with operating and planned cosmic-ray and neutrino detectors, and on the prospects of testing for neutrino properties.

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.
