On the nature of gamma-ray burst time dilations [PDF]

open access: yes, 1994
The recent discovery that faint gamma-ray bursts are stretched in time relative to bright ones has been interpreted as support for cosmological distances: faint bursts have their durations redshifted relative to bright ones.

Short gamma-ray bursts at the dawn of the gravitational wave era [PDF]

open access: yes, 2016
We derive the luminosity function and redshift distribution of short Gamma Ray Bursts (SGRBs) using (i) all the available observer-frame constraints (i.e.

A long-duration gamma-ray burst with a peculiar origin [PDF]

open access: yesNature, 2022
It is generally believed that long-duration gamma-ray bursts (GRBs) are associated with massive star core collapse1, whereas short-duration GRBs are associated with mergers of compact star binaries2.

Compton Dragged Gamma--Ray Bursts associated with Supernovae [PDF]

open access: yes, 1999
It is proposed that the gamma-ray photons that characterize the prompt emission of Gamma-Ray Bursts are produced through the Compton drag process, caused by the interaction of a relativistic fireball with a very dense soft photon bath.

Cosmic Ray and Neutrino Emission from Gamma-Ray Bursts with a Nuclear Cascade [PDF]

open access: yes, 2017
We discuss neutrino and cosmic-ray emission from Gamma-Ray Bursts (GRBs) with the injection of nuclei, where we take into account that a nuclear cascade from photo-disintegration can fully develop in the source.

Spectral Hardness and Evolution of Swift Gamma-Ray Bursts and X-Ray Afterglows

open access: yesThe Astrophysical Journal, 2023
Spectral hardness of gamma-ray bursts can be characterized by either hardness ratio or peak energy, and the inconsistency of these parameters can reflect spectral diversity and complexity.

Anisotropy in the sky distributions of the short and intermediate gamma-ray bursts: Breakdown of the cosmological principle? [PDF]

open access: yes, 2009
After the discovery of the anisotropy in the sky-distribution of intermediate gamma-ray bursts recently also the distribution of the short gamma-ray bursts is proven to be anisotropic.

Afterglow Polarization from Off-axis Gamma-Ray Burst Jets

open access: yesThe Astrophysical Journal, 2023
As we further our studies on gamma-ray bursts (GRBs), via both theoretical models and observational tools, more and more options begin to open for exploration of its physical properties.

Construction of the Variability -> Luminosity Estimator [PDF]

open access: yes, 2001
We present a possible Cepheid-like luminosity estimator for the long-duration gamma-ray bursts based on the variability of their light curves.Comment: To appear in Procs.

AN ALL-SKY SEARCH FOR THREE FLAVORS OF NEUTRINOS FROM GAMMA-RAY BURSTS WITH THE ICECUBE NEUTRINO OBSERVATORY [PDF]

open access: yes, 2016
We present the results and methodology of a search for neutrinos produced in the decay of charged pions created in interactions between protons and gamma-rays during the prompt emission of 807 gamma-ray bursts (GRBs) over the entire sky.
