Constraining Circum-burst Environments of GRBs with Jet Break Features in X-ray Afterglows
Si-Ji Xin, Yu-Qi Zhou, Sheng-Jin Sun +6
The nature of the circum-burst medium serves as a key diagnostic for probing the progenitor systems and the physics of relativistic jet propagation in gamma-ray bursts (GRBs). In t…
Extreme PeV accelerator associated with GRS 1915+105
Zhen Cao, F. Aharonian, Y. X. Bai +322
Microquasars, binary systems featuring relativistic jets, have emerged as sources for particle acceleration beyond PeV energies. We present a study of the broadband -ray emissi…
EP251023a: A fast X-ray transient featuring a magnetar-powered optical internal plateau followed by a steep decay
Shuai-Qing Jiang, Dong Xu, Wei-Hua Lei +33
EP251023a is an extragalactic fast X-ray transient (eFXT) detected solely by EP without a gamma-ray counterpart. The prompt emission consists of a main emission with a duration $T_…
Revisiting the Reported Period of FRB 20201124A Using MCMC Methods
Jun-Yi Shen, Yuan-Chuan Zou
Fast radio bursts (FRBs) are millisecond-duration radio transients whose physical origin remains uncertain. Magnetar-based models, motivated by observed properties such as polariza…
Hurst index of gamma-ray burst light curves and its statistical study
Ruo-Yu Guan, Fei-Fei Wang, Yuan-Chuan Zou
Gamma-ray bursts (GRBs) rank among the most powerful astrophysical phenomena, characterized by complex and highly variable prompt emission light curves that reflect the dynamics of…
Micro-Tidal Disruption Events at Galactic Centers
Xinyu Li, Houyi Sun, Yuan-Chuan Zou +1
This work explores a scenario for micro-tidal disruption events (TDEs) triggered by close encounters between high-speed white dwarfs (WDs) and stellar-mass black holes (sBHs) in ga…
