A pulsar escaping an ancient open cluster via tidal stripping
Lei Zhang, Xiaoting Fu, Di Li +21
Open clusters are the primary birthplaces of stars in the Milky Way disk, yet their neutron star progeny are rarely found within them, presumably due to supernova-induced kicks tha…
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)…
An Attempt to Search for Unintended Electromagnetic Radiation from Starlink Satellites with the 21 Centimeter Array: Methodology and RFI Characterization
Xupiao Yang, Qijun Zhi, Yanbin Yang +6
The rapid expansion of low-Earth-orbit (LEO) megaconstellations introduces new risks to radio astronomy from unintended electromagnetic radiation (UEMR). In this work, we present a…
Radio frequency interference identification using eigenvalue decomposition for multi-beam observations
Juntao Bai, Shi Dai, Na Wang +10
With the installation of next-generation phased array feed (PAF) receivers on radio telescopes, there is an urgent need to develop effective and computationally efficient radio fre…
Discovery of 15 new pulsars at high Galactic Latitudes with FAST
Xin Xu, Shi Dai, Qijun Zhi +9
We present the discovery and timing results of 15 pulsars discovered in a high Galactic latitude survey conducted with the Five-hundred-meter Aperture Spherical Telescope (FAST). T…
