Testing Weak Equivalence Principle with IceCube Event and Blazar
Tian-Cong Wang, Aleksandra Piorkowska - Kurpas, Marek Biesiada +1
Einstein's Weak Equivalence Principle (WEP), the universality of free fall, is a fundamental component of general relativity and other metric theories of gravity. Its validity can…
A Candidate Open Cluster Pulsar: Timing Analysis of PSR J1922+3745 in NGC 6791
Xiao-Jin Liu, Ralph P. Eatough, Zhichen Pan +15
PSR J1922+3745 was recently identified as a radio pulsar toward the old open cluster NGC 6791, raising the prospect of the first pulsar associated with an open cluster. We report F…
SSC Radiation in the ICMART Model: Spectral Simulations and Application to the Record-Breaking GRB 221009A
Xueying Shao, He Gao
This paper presents simulations of the synchrotron self-Compton (SSC) spectrum within the Internal-Collision-induced Magnetic Reconnection and Turbulence (ICMART) model. We investi…
The Head-on Collision of a Neutron Star with a White Dwarf
Zong-kai Peng, He Gao, Xian-Fei Zhang
We have computed the physical processes involved in a head-on collision between a neutron star (NS) and a white dwarf (WD). The outcomes of such collisions vary depending on the ma…
Comparative Statistical Analysis of Prompt and Afterglow X-Ray Flares in Gamma-Ray Bursts: Insights into Extended Central Engine Activity
Yinuo Ma, He Gao
Gamma-ray bursts (GRBs) are the most energetic phenomena in the Universe, characterized by prompt gamma-ray emission followed by multiwavelength afterglows. X-ray flares, observed…
Prospect of Gamma-Ray Burst Neutrino Detection with Enhanced Neutrino Detectors
Wenkang Lian, Shunke Ai, He Gao
Gamma-ray bursts (GRBs) have long been proposed as a potential source of high-energy neutrinos. Although no confirmed association between GRBs and neutrinos has been established, m…
