Morphology of Optical Changing-Look AGN-host Galaxies: Evidence for an Important Role of Mergers
Jie Tian, Yinghe Zhao, Jin-Ming Bai +1
Optical changing-look active galactic nuclei (CL-AGNs) are characterized by the (dis)appearance of broad emission lines on unexpectedly short timescales. However, the underlying me…
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)…
Cosmological distance forecasts for the CSST Galaxy Survey using BAO peaks
Feng Shi, Jieyi Tian, Zhejie Ding +21
The measurement of cosmological distances using baryon acoustic oscillations (BAO) is crucial for studying the universe's expansion. The Chinese Space Station Telescope (CSST) gala…
