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)…
Kepler K2 Observations of the Intermediate Polar FO Aquarii
M. R. Kennedy, P. Garnavich, E. Breedt +5
We present photometry of the intermediate polar FO Aquarii obtained as part of the K2 mission using the Kepler space telescope. The amplitude spectrum of the data confirms the orbi…
