Detection and Characterization of Quasi-Periodic Oscillations in Seyfert Galaxy NGC 4151
Yan Yongkang, Zhang Peng, Lu Zhou +6
This study aims to detect and characterize quasi-periodic oscillations (QPOs) signals in X-ray observations of NGC 4151. We employed the Weighted Wavelet Z-transform (WWZ) and Lomb…
An X-ray high-frequency quasi-periodic oscillation in NGC 1365
Yongkang Yan, Peng Zhang, Qingzhong Liu +4
This study presents the detection of a high-frequency quasi-periodic oscillation (QPO) in the Seyfert galaxy NGC 1365 based on observational data obtained by \emph{XMM-Newton} in J…
Multiwavelength observations of KS 1947+300
Wei Liu, Pablo Reig, Jingzhi Yan +5
KS 1947+300 is a Be/X-ray binary. Despite its nearly circular orbit, it displays both giant and regular less intense X-ray outbursts. According to the viscous decretion disk model,…
Multiwavelength observation of 1A 0535+262=HD 245770 from 2010 to 2021
Wei Liu, Jingzhi Yan, Guangcheng Xiao +3
Context. 1A 0535+262 is a high-mass X-ray binary that went into a giant X-ray outburst in 2020. During this event, the X-ray luminosity reached the highest value measured over the…
Sciences with the 2.5-meter Wide Field Survey Telescope (WFST)
WFST Collaboration, Tinggui Wang, Guilin Liu +60
The Wide Field Survey Telescope (WFST) is a dedicated photometric surveying facility being built jointly by the University of Science and Technology of China and the Purple Mountai…
Multiwavelength observations of Swift J0243.6+6124 from 2017 to 2022
Wei Liu, Jingzhi Yan, Pablo Reig +8
We have obtained optical spectroscopy and photometry data during four years after the event. The long-term photometric light-curve and the equivalent widths of the Halpha and He I…
