Multiwavelength Analysis of the Einstein Probe X-ray Transient EP240305a
Ruican Ma, Ye Li, Lian Tao +32
We report multiwavelength observations of EP240305a, an uncatalogued X-ray transient detected by the Einstein Probe on March 5, 2024. The source exhibits distinct characteristics a…
The Origin of Cross-Energy-Similar FRED Profiles in Gamma-Ray Bursts Pulses
Shu-Xu Yi, Chen-Wei Wang, Shao-Lin Xiong +5
To understand the physical mechanisms underlying the prompt emission of gamma-ray bursts (GRB), single FRED (Fast-Rise-Exponential-Decay) profile GRBs serve as an ideal sample, as…
Accretion-modified Stars in Accretion Disks of Active Galactic Nuclei: Contribution to AGN disk viscosity
Jun-Rong Liu, Jian-Min Wang, Hua Feng
It is widely believed that stellar-mass black holes (sMBHs) exist within the accretion disks of active galactic nuclei (AGN), forming a distinct population termed ``accretion-modif…
A Common Synchrotron Origin for Prompt Gamma-Ray and Soft X-Ray Emission in GRBs: Evidence from Joint Spectral Analysis
Ziming Wang, Chenyu Wang, He Gao +4
The recent launches of the Einstein Probe (EP) and the Space Variable Objects Monitor (SVOM) mission have led to the detection of a growing number of long GRBs with significant, ea…
