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…
Are Repeaters Prevalent Among the Known Fast Radio Burst Sources?
Xiao-Fei Dong, Qing Pan, Yong-Feng Huang +10
Fast radio bursts (FRBs) are millisecond radio pulses of unknown origin. Despite extensive follow-up observations, only of FRBs have been confirmed as repeaters. It remai…
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…
Magnetic Reconnection as a Potential Driver of X-ray Variability in Active Galactic Nuclei
Chen-Ran Hu, Yong-Feng Huang, Lang Cui +13
We present a systematic analysis on the X-ray variability in 13 bright quasars at z > 4.5, combining recent Swift observations from 2021 to 2023 and archival multi-epoch observatio…
Second-scale periodicity in FRB 20201124A: coincident with critical RM evolution epochs and its possible implications
Wen-Long Zhang, Chen-Ran Hu, Chen Du +13
Second-timescale periodicity (1.7\,s) has been reported in the repeating fast radio burst FRB\,20201124A during two epochs, MJD\,59310 and MJD\,59347. We find that these two…
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…
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…
Spin resolved momentum spectra for vacuum pair production via a generalized two level model
Orkash Amat, Hong-Hao Fan, Suo Tang +2
We have formulated a generalized two level model for studying the pair production in multidimensional time-dependent electric fields. It can provide momentum spectra with fully spi…
A Comprehensive Analysis on Repeating Fast Radio Bursts
Chen-Ran Hu, Yong-Feng Huang
Nearly 700 fast radio burst (FRB) sources have been detected till now, among which 29 FRBs are found to burst out repeatedly. Although a firm connection between at least some FRBs…
Gravitational-wave Emission from a Primordial Black Hole Inspiraling inside a Compact Star: a Novel Probe for Dense Matter Equation of State
Ze-Cheng Zou, Yong-Feng Huang
Primordial black holes of planetary masses captured by compact stars are widely studied to constrain their composition fraction of dark matter. Such a capture may lead to an inspir…
