Populations III.1 and III.2 gamma-ray bursts: constraints on the event rate for future radio and X-ray surveys
(EDP SCIENCES S A, 2011)
Aims. We calculate the theoretical event rate of gamma-ray bursts (GRBs) from the collapse of massive first-generation (Population III; Pop III) stars. The Pop III GRBs could be super-energetic with the isotropic energy ...
Solar submillimeter and gamma-ray burst emission

Hot gas around SN 1998bw: inferring the progenitor from its environment
(EDP Sciences, 2017)
Spatially resolved spectroscopy of the environments of explosive transients carries detailed information about the physical properties of the stellar population that gave rise to the explosion, and thus the progenitor ...
Neutrinos from collapsars

The supernova of the MAGIC gamma-ray burst GRB 190114C
(EDP Sciences, 2022-03)
We observed GRB 190114C (redshift z = 0.4245), the first gamma-ray burst (GRB) ever detected at TeV energies, at optical and near-infrared wavelengths with several ground-based telescopes and the Hubble Space Telescope, ...
Study of the relationship between the gamma ray bursts and their host galaxies
(Asociación Argentina de Astronomía, 2005-09)
Gamma ray bursts (GRBs) belong to the most energetic events in the Universe. Recently, the extragalactic nature of these sources has been confirmed with the discovery of several host galaxies (HGs) and the measurement of ...
Effects of high-energy astrophysical events on habitable planets
(CAMBRIDGE UNIV PRESSNEW YORK, 2012)
With the possible exception of meteor impacts, high-energy astrophysical events such as supernovae, gamma-ray bursts (GRB) and flares are usually not taken into account for biological and evolutionary studies due to their ...
The metallicity and star formation activity of Long Gamma Ray Burst hosts for z<3: Insights from the Illustris Simulation.
(Wiley Blackwell Publishing, Inc, 2017-05)
We study the properties of long gamma-ray bursts (LGRBs) using a large scale hydrodynamical cosmological simulation, the Illustris simulation. We determine the LGRB host populations under different thresholds for the LGRB ...
The host galaxies of long-duration gamma-ray bursts in a cosmological hierarchical scenario
(Oxford University Press, 2007-02)
We developed a Monte Carlo code to generate long-duration gamma-ray burst (LGRB) events within cosmological hydrodynamical simulations consistent with the concordance Λ cold dark matter model. As structure is assembled, ...
