Time delay between neutrinos and gamma-rays in short gamma-ray bursts
(Institute of Physics Publishing, 2019-02)
In this Letter we make an estimate of the time delay between signals, recorded at detectors on Earth, of neutrinos and photons originated in a short gamma-ray burst. We describe the geometry and dynamics of the system ...
GRB 140606B/iPTF14bfu: detection of shock-breakout emission from a cosmological gamma-ray burst?
(OXFORD UNIV PRESS, 2015)
We present optical and near-infrared photometry of GRB 140606B (z = 0.384), and optical photometry and spectroscopy of its associated supernova (SN). The results of our modelling indicate that the bolometric properties of ...
GRB 161219B/SN 2016jca: a low-redshift gamma-ray burst supernova powered by radioactive heating
(EDP Sciences, 2017)
Since the first discovery of a broad-lined type Ic supernova (SN) with a long-duration gamma-ray burst (GRB) in 1998, fewer than fifty GRB-supernovae (SNe) have been discovered. The intermediate-luminosity Swift GRB 161219B ...
The 80 Ms follow-up of the X-ray afterglow of GRB 130427A challenges the standard forward shock model
(OXFORD UNIV PRESS, 2016)
GRB 130427A was the brightest gamma-ray burst detected in the last 30 yr. With an equivalent isotropic energy output of 8.5 x 10(53) erg and redshift z = 0.34, it uniquely combined very high energetics with a relative ...
Metallicity effects in long gamma-ray burst populations in a ΛCDM Universe
(Elsevier Science, 2018-11)
The use of long γ-ray burst as star formation tracers is suspected to be affected by a possible dependence of the production or luminosity of these sources on the metallicity of their stellar progenitors. Selection effects ...
