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

Gamma-Ray Burst Prompt Correlations [PDF]

Advances 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.

A nearby long gamma-ray burst from a merger of compact objects. [PDF]

Nature, 2022
Gamma-ray bursts (GRBs) are flashes of high-energy radiation arising from energetic cosmic explosions. Bursts of long (greater than two seconds) duration are produced by the core-collapse of massive stars1, and those of short (less than two seconds ...

A lanthanide-rich kilonova in the aftermath of a long gamma-ray burst [PDF]

Nature, 2023
Observationally, kilonovae are astrophysical transients powered by the radioactive decay of nuclei heavier than iron, thought to be synthesized in the merger of two compact objects1-4.

A Kilonova Following a Long-Duration Gamma-Ray Burst at 350 Mpc [PDF]

Nature, 2022
Gamma-ray bursts (GRBs) are divided into two populations1,2; long GRBs that derive from the core collapse of massive stars (for example, ref. 3) and short GRBs that form in the merger of two compact objects4,5.

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.

Gamma-Ray Burst Progenitors [PDF]

Space Science Reviews, 2016
We review our current understanding of the progenitors of both long and short duration gamma-ray bursts (GRBs). Constraints can be derived from multiple directions, and we use three distinct strands; (i) direct observations of GRBs and their host ...

Fast Radio Burst/Gamma-Ray Burst Cosmography [PDF]

, 2014
Recently, both theoretical arguments and observational evidence suggested that a small fraction of fast radio bursts (FRBs) could be associated with gamma-ray bursts (GRBs).
