Diverse Morphologies of GRB X-Ray Plateaus within a Common Magnetar Framework
Xiao-Fei Dong, Yong-Feng Huang, Nurimangul Nurmamat +7
The origin of the X-ray plateau phase in gamma-ray bursts (GRBs) remains an open problem. In particular, it is unclear whether GRBs with different temporal morphologies (i.e., with…
A second-scale periodicity in an active repeating fast radio burst source
Chen Du, Yong-Feng Huang, Jin-Jun Geng +14
Fast radio bursts (FRBs) are fierce radio flashes from the deep sky. Abundant observations have indicated that highly magnetized neutron stars might be involved in these energetic…
A Statistical Analysis of Fluence and Energy Distributions of Non-repeating Fast Radio Bursts Detected by CHIME
Nurimangul Nurmamat, Yong-Feng Huang, Xiao-Fei Dong +6
Fast Radio Bursts (FRBs) are energetic radio bursts that typically last for milliseconds. They are mostly of extragalactic origin, but the progenitors, trigger mechanisms and radia…
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…
Two Periodic Activity Epochs in FRB 20201124A: Coincident with Critical RM Evolution Epochs and Its Implications
Wen-Long Zhang, Chen-Ran Hu, Chen Du +12
Recent observations of the repeating fast radio burst FRB 20201124A by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) revealed a second-scale periodic modulation…
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,…
