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

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

Optical and Near-infrared Observations of the Distant but Bright “New Year’s Burst” GRB 220101A
The Astrophysical Journal, 2023 High-redshift gamma-ray bursts (GRBs) are useful to probe the early Universe, but only a few candidates have been detected so far. Here, we report the optical and near-infrared observations of the afterglow of a relatively high-redshift event GRB 220101A,

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

Construction of the Variability -> Luminosity Estimator [PDF]
, 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]
, 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.

Energetics of Gamma‐Ray Bursts [PDF]
The Astrophysical Journal, 2001 We determine the distribution of total energy emitted by gamma-ray bursts for bursts with fluences and distance information. Our core sample consists of eight bursts with BATSE spectra and spectroscopic redshifts. We extend this sample by adding four bursts with BATSE spectra and host galaxy R magnitudes. From these R magnitudes we calculate a redshift

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