Constraining the Supernova Remnant Environment of FRB 190520B with Dispersion Measure and Scattering Timescale
Jia-Peng Wei, Chen Deng, Gwenael Giacinti +4
FRB 190520B is a repeating fast radio burst source whose large dispersion measure (DM) and temporal broadening suggest a dense and evolving local environment. In this work, we test…
An Intertwined Short and Long GRB with 4-minute Separation
Liang Li, Yu Wang, Bing Zhang +19
Gamma-ray bursts (GRBs), the most energetic transients in the Universe, are traditionally classified into long-duration ( s) and short-duration ( s) events, ass…
Pulse-resolved Classification and Characteristics of Long-duration GRBs with \emph{Swift}-BAT Data.I. Precursors versus Main Bursts
Liang Li, Yu Wang, Jin-Jun Geng +2
We present a systematic pulse-by-pulse analysis of 22 long-duration GRBs observed by \emph{Swift}, each exhibiting a well-separated precursor before the main burst. We compare dura…
Axial current as the origin of quantum intrinsic orbital angular momentum
Orkash Amat, Nurimangul Nurmamat, Yong-Feng Huang +9
We show that the axial current density is the physical origin (generator) of quantum intrinsic orbital angular momentum (IOAM). Without the axial current, the IOAM of particles van…
The Soft X-ray Aspect of Gamma-ray Bursts in the Einstein Probe Era
Hao-Xuan Gao, Jin-Jun Geng, Yi-Fang Liang +6
The Einstein Probe (EP) satellite, dedicated at time-domain high-energy astrophysics and multi-messenger astronomy, was recently launched and successfully put into operation. The w…
Generalized quantum two level model and its application in astrophysics
Orkash Amat, Nurimangul Nurmamat, Yong-Feng Huang +9
Complicated time-dependent curved spacetime and electric field are involved in many astrophysical situations, including the early universe, Hawking radiation, the Schwinger effect,…
