The annular gap model under a rotating dipole field approximation: simulating gamma-ray light curve

Jie Tian, Xin Xu, Qijun Zhi +5

A more realistic description of the magnetosphere is crucial for understanding the radiation emitted by pulsars. In this paper, we revisit the annular gap model by employing a rota…

RRAT J1541+4703: A Rotating Radio Transient Exhibiting Normal Pulsar States

Xin Xu, Qijun Zhi, Jie Tian +6

Rotating Radio Transients (RRATs) are a class of pulsar-like objects characterized by intermittent radio emissions. Among them, RRATs that exhibit both RRAT and normal pulsar (NP)…

The Study of Mode Switching behavior of PSR J0614+2229 Using the Parkes Ultra-wideband Receiver Observations

Yanqing Cai, Shijun Dang, Rai Yuen +21

In this paper, we presented a detailed single pulse and polarization study of PSR J0614+2229 based on the archived data observed on 2019 August 15 (MJD 58710) and September 12 (MJD…

Investigating the multi-drifting behavior of subpulses in PSR J20070910 with the FAST

Xin Xu, Lunhua Shang, Qijun Zhi +7

The multi-drifting subpulse behaviors in PSR J2007+0910 have been studied carefully with the high sensitivity observations of the Five-hundred-meter Aperture Spherical radio Telesc…

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…
