Fast radio bursts generated by coherent curvature radiation from compressed bunches for FRB 20190520B
Xiang-han Cui, Zheng-wu Wang, Cheng-min Zhang +4
The radiation mechanism of fast radio bursts (FRBs) has been extensively studied but still remains elusive. Coherent radiation is identified as a crucial component in the FRB mecha…
The Minimum Variation Timescales of X-ray bursts from SGR J1935+2154
Shuo Xiao, Jiao-Jiao Yang, Xi-Hong Luo +34
The minimum variation timescale (MVT) of soft gamma-ray repeaters can be an important probe to estimate the emission region in pulsar-like models, as well as the Lorentz factor and…
Discovery of the linear energy-dependence of the spectral lag of X-ray bursts from SGR J1935+2154
Shuo Xiao, You-Li Tuo, Shuang-Nan Zhang +31
Spectral lag of the low-energy photons with respect to the high-energy ones is a common astrophysical phenomenon (such as Gamma-ray bursts and the Crab pulsar) and may serve as a k…
Distribution of fast radio burst dispersion measures in CHIME/FRB Catalog 1: implications on the origin of FRBs
Jianwei Zhang, Chengmin Zhang, Di Li +7
Recently, CHIME/FRB project published its first fast radio burst (FRB) catalog (hereafter, Catalog 1), which totally contains 536 unique bursts. With the help of the latest set of…
Evolution of Spin Period and Magnetic Field of the Crab Pulsar: Decay of the Braking Index by the Particle Wind Flow Torque
Cheng-Min Zhang, Xiang-Han Cui, Di Li +8
The evolutions of a neutron star's rotation and magnetic field (B-field) have remained unsolved puzzles for over half a century. We ascribe the rotational braking torques of pulsar…
Search for Quasi-Periodical Oscillations in Precursors of Short and Long Gamma Ray Bursts
Shuo Xiao, Wen-Xi Peng, Shuang-Nan Zhang +23
The precursors of short and long Gamma Ray Bursts (SGRBs and LGRBs) can serve as probes of their progenitors, as well as shedding light on the physical processes of mergers or core…
Luminosity distribution of fast radio bursts from CHIME/FRB Catalog 1 by means of the updated Macquart relation
Xiang-Han Cui, Cheng-Min Zhang, Di Li +9
Fast radio bursts (FRBs) are extremely strong radio flares lasting several micro- to milliseconds and come from unidentified objects at cosmological distances, most of which are on…
Statistical tests of young radio pulsars with/without supernova remnants: implying two origins of neutron stars
Xiang-Han Cui, Cheng-Min Zhang, Di Li +11
The properties of the young pulsars and their relations to the supernova remnants (SNRs) have been the interesting topics. At present, 383 SNRs in the Milky Way galaxy have been pu…
Statistical properties of fast radio bursts elucidate their origins: magnetars are favoured over gamma-ray bursts
Xiang-Han Cui, Cheng-Min Zhang, Shuang-Qiang Wang +11
Fast radio bursts (FRBs) are extremely strong radio flares lasting several milliseconds, most of which come from unidentified objects at a cosmological distance. They can be appare…
Fast radio bursts: do repeaters and non-repeaters originate in statistically similar ensembles
Xiang-Han Cui, Cheng-Min Zhang, Shuang-Qiang Wang +9
Fast Radio Bursts (FRBs) are the short, strong radio pulses lasting several milliseconds. They are subsequently identified, for the most part, as emanating from unknown objects at…
Evolution implications of neutron star magnetic fields: inferred from pulsars and cyclotron lines of HMXBs
Chang-Qing Ye, De-Hua Wang, Cheng-Min Zhang +1
The evolution of neutron star (NS) magnetic field (B-field) has long been an important topic, which is still not yet settled down. Here, we analyze the NS B-fields inferred by the…
