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

open access: yesNature 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

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

open access: yesNature 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.

Gamma-Ray Burst Prompt Correlations [PDF]

open access: yesAdvances in Astronomy, 2018
The mechanism responsible for the prompt emission of gamma-ray bursts (GRBs) is still a debated issue. The prompt phase-related GRB correlations can allow discriminating among the most plausible theoretical models explaining this emission.

The GRB221009A gamma-ray burst as revealed by the gamma-ray spectrometer onboard the KPLO (Danuri) [PDF]

open access: yesScientific Reports
The strongest gamma-ray burst (GRB) of the century, GRB20221009A, has been detected by the Korean Pathfinder Lunar Orbiter Gamma-ray Spectrometer (KGRS) instrument onboard the Korean Pathfinder Lunar Orbiter (KPLO).

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

open access: yesScience, 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 ...

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.
