We provide a comprehensive review of major developments in our understanding of gamma-
ray bursts, with particular focus on the discoveries made within the last fifteen years when …

Connection between energy-dependent lags and peak luminosity in gamma-ray bursts

JP Norris, GF Marani, JT Bonnell - The Astrophysical Journal, 2000 - iopscience.iop.org
We suggest a connection between the pulse paradigm at gamma-ray energies and the
recently demonstrated luminosity distribution in gamma-ray bursts: The spectral evolution …

Predictions for the very early afterglow and the optical flash

T Piran - The Astrophysical Journal, 1999 - iopscience.iop.org
According to the internal-external shocks model for gamma-ray bursts (GRBs), the GRB is
produced by internal shocks within a relativistic flow while the afterglow is produced by …

Discerning the physical origins of cosmological gamma-ray bursts based on multiple observational criteria: the cases of z= 6.7 GRB 080913, z= 8.2 GRB 090423, and …

B Zhang, BB Zhang, FJ Virgili, EW Liang… - The Astrophysical …, 2009 - iopscience.iop.org
The two high-redshift gamma-ray bursts, GRB 080913 at z= 6.7 and GRB 090423 at z= 8.2,
recently detected by Swift appear as intrinsically short, hard GRBs. They could have been …

An unexpectedly rapid decline in the X-ray afterglow emission of long γ-ray bursts

G Tagliaferri, M Goad, G Chincarini, A Moretti… - Nature, 2005 - nature.com
Abstract 'Long'γ-ray bursts (GRBs) are commonly accepted to originate in the explosion of
particularly massive stars, which give rise to highly relativistic jets. Inhomogeneities in the …

A systematic analysis of supernova light in gamma-ray burst afterglows

A Zeh, S Klose, DH Hartmann - The Astrophysical Journal, 2004 - iopscience.iop.org
We systematically reanalyzed all gamma-ray burst (GRB) afterglow data published through
the end of 2002 in an attempt to detect the predicted supernova light component and to gain …

Prompt and delayed emission properties of gamma-ray bursts observed with BeppoSAX

F Frontera, L Amati, E Costa, JM Muller… - The Astrophysical …, 2000 - iopscience.iop.org
We investigated the spectral evolution in the 2–700 keV energy band of gamma-ray bursts
(GRBs) detected by the Gamma-Ray Burst Monitor (GRBM) and localized with the Wide …

A standard kinetic energy reservoir in gamma-ray burst afterglows

E Berger, SR Kulkarni, DA Frail - The Astrophysical Journal, 2003 - iopscience.iop.org
We present a comprehensive sample of X-ray observations of 41 γ-ray burst (GRB)
afterglows, as well as jet opening angles, &thetas; j, for a subset with measured jet breaks …

Early X-ray flares in GRBs

R Ruffini, Y Wang, Y Aimuratov… - The Astrophysical …, 2018 - iopscience.iop.org
We analyze the early X-ray flares in the GRB" flare–plateau–afterglow"(FPA) phase
observed by Swift-XRT. The FPA occurs only in one of the seven GRB subclasses: the …

The morphology of the X-ray afterglows and of the jetted GeV emission in long GRBs

R Ruffini, R Moradi, JA Rueda, L Li… - Monthly Notices of …, 2021 - academic.oup.com
We recall evidence that long gamma-ray bursts (GRBs) have binary progenitors and give
new examples. Binary-driven hypernovae (BdHNe) consist of a carbon–oxygen core …
