Observational Properties of Nonthermal Emission from Relativistic Jets Escaping Active Galactic Nucleus Disks
Ken Chen, Zi-Gao Dai
Relativistic jets launched from stellar-mass compact objects embedded in the accretion disk of an active galactic nucleus (AGN) can produce nonthermal emission upon successfully br…
Periodic Emission Frequency Modulation in a Hyperactive Fast Radio Burst
Rui-Nan Li, Hao-Tian Lan, Zhen-Yin Zhao +3
Fast radio bursts (FRBs) are intense, short-duration radio transients of mysterious origin. They have been detected across a wide range of frequencies from 110 MHz to 8 GHz. Their…
A White Dwarf Tidal Disruption by an Intermediate-Mass Black Hole as the Progenitor of Ultra-long GRB 250702B
Chengchao Yuan, Ning Jiang, Zi-Gao Dai
The recent detection of GRB 250702B, the longest gamma-ray burst observed to date with prompt emission lasting seconds, challenges the conventional collapsar…
Pulse-resolved Classification and Characteristics of Long-duration GRBs with \emph{Swift}-BAT Data.II. Main Burst versus Extended Emission
Liang Li, Xiao Wang, Zhi-Li Cui +5
Long gamma-ray bursts (GRBs) frequently exhibit complex prompt emission structures with multiple temporally distinct episodes, such as a main emission (ME) phase followed by a weak…
Stellar Wind-Blown Bubbles as Environments for Late-Time Rebrightening of Gamma-Ray Burst Afterglows
Jia Ren, Xiao-Yan Li, Yun Wang +5
We presented the multi-wavelength afterglow fitting results for three events that exhibit late afterglow rebrightening behavior: EP240414a (), GRB 240529A (), and…
Super-Eddington Magnetized Neutron Star Accretion Flows: a Self-similar Analysis
Ken Chen, Zi-Gao Dai
The properties of super-Eddington accretion disks exhibit substantial distinctions from the sub- Eddington ones. In this paper, we investigate the accretion process of a magnetized…
Multiwavelength Radiation from the Interaction between Magnetar Bursts and Companion Star in a Binary System
Yu-Jia Wei, Yuan-Pei Yang, Da-Ming Wei +1
Magnetars are young, highly magnetized neutron stars that are associated with magnetar short bursts (MSBs), magnetar giant flares (MGFs), and at least some fast radio bursts (FRBs)…
