Energy-dependent intrinsic time delay of gamma-ray bursts on testing Lorentz invariance violation

Physics Letters B
High-energy photons of gamma-ray bursts (GRBs) might be emitted at different intrinsic times with energy dependence at the source. In this letter, we expand the model from previous works on testing the Lorentz Invariance Violation (LV) with the observed ...

Time-averaging Polarimetric and Spectral Properties of Gamma-Ray Bursts

The Astrophysical Journal Supplement Series
The composition and radiation mechanism of gamma-ray bursts (GRBs) within jets continue to be hotly debated. Investigating the joint polarimetric and spectral properties is crucial for understanding the composition and radiation mechanism of GRBs ...

Probing a Cosmogenic Origin of Astrophysical Neutrinos and Cosmic Rays Using Gamma-Ray Observations of TXS 0506+056

The Astrophysical Journal
In 2017 September, a high-energy neutrino event detected by the IceCube Neutrino Observatory (IceCube-170922A) was associated, at the 3 σ level, with a gamma-ray flare from the blazar TXS 0506+056.

Subphotospheric dissipation in gamma-ray bursts observed by the Fermi Gamma-ray Space Telescope

, 2016
Gamma-ray bursts (GRBs) are the brightest events in the Universe, for a short time outshining the rest of the Universe combined, as they explode with isotropic equivalent luminosities up to $10^{54}$ erg s$^{-1}$. These events are believed to be connected to supernovae and to binary compact object mergers, such as binary neutron stars or neutron star --
