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

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.

BINARY NEUTRON STAR MERGERS: A JET ENGINE FOR SHORT GAMMA-RAY BURSTS. [PDF]

Astrophys J Lett, 2016
We perform magnetohydrodynamic simulations in full general relativity (GRMHD) of quasi-circular, equal-mass, binary neutron stars that undergo merger. The initial stars are irrotational, n = 1 polytropes and are magnetized.

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 ...

Outliers in Spectral Time Lag-Selected Gamma Ray Bursts

Universe, 2022
It is possible that astrophysical samples are polluted by some outliers, which might belong to a different sub-class. By removing the outliers, the underlying statistical features may be revealed.
