A General Overview for Localizing Short Gamma-Ray Bursts with a CubeSat Mega-Constellation [PDF]
Frontiers in Astronomy and Space Sciences, 2020 The gamma-ray burst monitor (GBM) on the Fermi Gamma-Ray Space Telescope, for the first time, detected a short gamma ray burst (SGRB) signal that accompanies a gravitational wave signal GW170817 in 2017.

Modeling the Gamma-Ray Burst Jet Properties with 3D General Relativistic Simulations of Magnetically Arrested Accretion Flows [PDF]
Astrophysical Journal, 2022 We investigate the dependence of the gamma-ray burst (GRB) jet structure and its evolution on the properties of the accreting torus in the central engine.

Investigating the gamma-ray burst from decaying MeV-scale axion-like particles produced in supernova explosions [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 We investigate the characteristics of the gamma-ray signal following the decay of MeV-scale Axion-Like Particles (ALPs) coupled to photons which are produced in a Supernova (SN) explosion.

The Dependence of Gamma-Ray Burst Jet Collimation on Black Hole Spin [PDF]
Astrophysical Journal Letters, 2023 Gamma-ray bursts (GRBs) are the most luminous events in the Universe and are excellent laboratories to study extreme physical phenomena in the cosmos. Despite a long trajectory of progress in understanding these highly energetic events, there are still ...

A peculiarly short-duration gamma-ray burst from massive star core collapse [PDF]
Nature Astronomy, 2021 Gamma-ray bursts (GRBs) have been phenomenologically classified into long and short populations based on the observed bimodal distribution of duration1. Multi-wavelength and multi-messenger observations in recent years have revealed that in general long ...

Jets in a Gamma-Ray Burst during Its Prompt Emission: Evolution of the Lorentz Factor [PDF]
Astrophysical Journal, 2022 Knowledge about the Lorentz factor and its evolution of relativistic jets in gamma-ray bursts (GRBs) is crucial to understand their physics. An exact value of the bulk Lorentz factor can be estimated based on a high-energy spectral cutoff, which may ...

A semi-analytical solution to the forward-reverse shock hydrodynamics of the gamma-ray burst afterglow [PDF]
, 2022 We extend the standard model of forward-reverse shock (FS-RS) for gamma-ray burst (GRB) afterglow to more general cases. On one hand, we derive the analytical solution to the hydrodynamics of the shocks in two limiting cases, i.e., an ultra-relativistic ...

Precollapse Properties of Superluminous Supernovae and Long Gamma-Ray Burst Progenitor Models [PDF]
Astrophysical Journal, 2020 We analyze the properties of 42 rapidly rotating, low-metallicity, quasi-chemically homogeneously evolving stellar models in the mass range between 4 and 45 at the time of core collapse.

Model-independent determination of H0 and ΩK, 0 using time-delay galaxy lenses and gamma-ray bursts [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Combining the ‘time-delay distance’ (DΔt) measurements from galaxy lenses and other distance indicators provides model-independent determinations of the Hubble constant (H0) and spatial curvature (ΩK, 0), only based on the validity of the Friedmann ...

The delay time of gravitational wave — gamma-ray burst associations [PDF]
Frontiers of Physics, 2019 The first gravitational wave (GW) — gamma-ray burst (GRB) association, GW170817/GRB 170817A, had an offset in time, with the GRB trigger time delayed by ∼1.7 s with respect to the merger time of the GW signal.
