Gamma-Ray Burst Prompt Correlations

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.

Present and future gamma-ray burst experiments [PDF]

open access: yes, 1998
Gamma-ray burst counterpart studies require small, prompt error boxes. Today, there are several missions which can provide them: BeppoSAX, the Rossi X-Ray Timing Explorer, and the 3rd Interplanetary Network.

Cosmology with gamma-ray bursts

open access: yesAstronomical and Astrophysical Transactions, 2022
Gamma-ray bursts constitute one of the most fascinating and relevant phenomena in modern science, with strong implications for several fields of astrophysics, cosmology and fundamental physics. In this short review, I focus on the prospective key-role of GRBs for cosmology. Indeed, the huge luminosity, the redshift distribution extending at least up

Supernovae and Gamma-ray Bursts [PDF]

open access: yesProceedings of the International Astronomical Union, 2011
AbstractThe properties of the Supernovae discovered in coincidence with long-duration Gamma-ray Bursts and X-Ray Flashes are reviewed, and compared to those of SNe for which GRBs are not observed. The SNe associated with GRBs are of Type Ic, they are brighter than the norm, and show very broad absorption lines in their spectra, indicative of high ...

Swift Pointing and Gravitational-Wave Bursts from Gamma-Ray Burst Events

open access: yes, 2003
The currently accepted model for gamma-ray burst phenomena involves the violent formation of a rapidly rotating solar-mass black hole. Gravitational waves should be associated with the black-hole formation, and their detection would permit this model to ...

COMPTEL observations of cosmic gamma‐ray bursts [PDF]

open access: yes, 1991
The imaging γ‐ray telescope COMPTEL on board NASA’s Compton Gamma‐Ray Observatory (GRO) has observed many cosmic gamma‐ray bursts during the early mission phase of GRO. COMPTEL records time‐resolved burst spectra over 0.1 MeV to 10 MeV energies, and, for

Are there MeV gamma-ray bursts? [PDF]

open access: yesAIP Conference Proceedings, 1996
It is often stated that gamma-ray bursts (GRBs) have typical energies of several hundred keV. Is this a real feature of GRBs or is it due to an observational bias? We consider the possibility that bursts of a given bolometric luminosity occur with a hardness distribution $p(H)d \log H \propto H^γd \log H$.

Polarized Emission from Gamma-Ray Burst Jets

open access: yesGalaxies, 2017
I review how polarization signals have been discussed in the research field of Gamma-Ray Bursts (GRBs). I mainly discuss two subjects in which polarimetry enables us to study the nature of relativistic jets.
