Simulating Short Gamma-Ray Burst Jets in Realistic Late Binary Neutron Star Merger Environments
Astrophysical JournalThe electromagnetic emission and the afterglow observations of the binary neutron star merger event GW170817A confirmed the association of the merger with a short gamma-ray burst (GRB) harboring a narrow (5°–10°) and powerful (1049–1050 erg) jet.

Microphysics in the Gamma-Ray Burst Central Engine
, 2016We calculate the structure and evolution of a gamma-ray burst central engine where an accreting torus has formed around the newly born black hole. We study the general relativistic, MHD models and we self-consistently incorporate the nuclear equation of ...

Building on a general relativistic magnetohydrodynamic simulation of a short gamma-ray burst (sGRB) jet with initial magnetization σ0 = 150, propagating through the dynamical ejecta from a binary neutron star merger, we identify regions of energy ...

Gamma-ray bursts generated from phase transition of neutron stars to quark stars
Modern Physics Letters A, 2017The evolution of compact stars is believed to be able to produce various violent phenomena in our universe. In this paper, we discuss the possibility that gamma-ray bursts (GRBs) might result from the phase transition of a neutron star to a quark star and calculate the energy released from the conversion. In our study, we utilize the relativistic mean

A broad energy range wide field monitor for next generation gamma-ray burst experiments
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2008A coded mask instrument based on Silicon Drift Detectors coupled to scintillators operated with a pulse shape discrimination technique is presented as a candidate wide field monitor for forthcoming gamma-ray burst (GRB) search missions. Such an instrument would allow an energy range extended from 1 keV to 1 MeV, in a single compact device, providing ...

The Ejection of Relativistic Bullets from Supernovae and the Generation of Gamma-Ray Bursts
The Astrophysical Journal, 2000It is generally believed that cosmological gamma-ray bursts (GRBs) are produced by the deceleration of relativistic objects with Gamma greater, similar100. We study the possibility that some GRBs are produced along with relativistic matter ejected from supernovae.

Generic difference between early and late stages of BATSE gamma-ray bursts
AIP Conference Proceedings, 2000The concept of early and late stages (ES and LS) of gamma-ray bursts is implemented for the statistical analysis of the large sample of BATSE events. The primary peak is proposed to be the boundary between the early and late stages of emission. Significant differences are found between ES and LS: the early stage is shorter than the late one, it has the

We report on a new analysis of instabilities in close neutron star binaries based upon (3+1) dimensional general relativistic numerical hydrodynamics calculations. When a realistic equation of state is employed, orbit calculations for two 1.45 M⊙ neutron stars reveal surprising evidence that general relativistic effects may cause otherwise stable stars
