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…

Gamma-Ray Bursts: Evidence for a Common Origin of X-ray Plateaus with Diverse Temporal Decay Index

Xiao-Fei Dong, Yong-Feng Huang, Chen Deng +8

A significant fraction of gamma-ray bursts (GRBs) exhibit a plateau in the early X-ray afterglow light curve, whose mechanism remains uncertain. While the post-plateau normal decay…

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…

A Statistical Study of the Gamma-Ray Burst and Supernova Association

Xiao-Fei Dong, Yong-Feng Huang, Zhi-Bin Zhang +5

The association between long gamma-ray bursts (LGRBs) and core-collapse supernovae (SNe) has been well established since the discovery of SN 1998bw, which was linked to the low-lum…

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…
