Constraints on the Low-frequency Radio Emission of the Galactic FRB Source SGR 1935+2154
Chen-Ran Hu, Jinhuang Cao, S. A. Tyul'bashev +13
We present a search for radio pulses from the Galactic magnetar SGR 1935+2154, a well-known source of fast radio bursts (FRBs), at 110 MHz using the Large Phased Array (LPA)…
A Missing Tool for Calculating Auto/Cross-correlation Function under Nonuniform Sampling Observations
Chen-Ran Hu, Yong-Feng Huang, Jin-Jun Geng +10
Nonuniform sampling presents a long-standing challenge in astrophysical time-domain analysis, invalidating the standard autocorrelation and cross-correlation functions and forcing…
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 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…
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,…
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…
