Mining for Candidates of Galactic Stellar-mass Black Hole Binaries with LAMOST
Tuan Yi, Mouyuan Sun, Wei-Min Gu
We study the prospects of searching for black hole (BH) binary systems with a stellar-mass BH and a non-compact visible companion, by utilizing the spectroscopic data of Large Sky…
Discovery of A Mg II Changing-look AGN and its Implications for a Unification Sequence of Changing-look AGNs
Hengxiao Guo, Mouyuan Sun, Xin Liu +5
Changing-Look (CL) is a rare phenomenon of Active Galactic Nuclei (AGNs) that exhibit emerging or disappearing broad lines accompanied by continuum variations on astrophysically sh…
Understanding Broad Mg II Variability in Quasars with Photoionization: Implications for Reverberation Mapping and Changing-Look Quasars
Hengxiao Guo, Yue Shen, Zhicheng He +7
The broad Mg II line in quasars has distinct variability properties compared with broad Balmer lines: it is less variable, and usually does not display a "breathing" mode, the incr…
On the Origin of the Dramatic Spectral Variability of WPVS 007
Junyao Li, Mouyuan Sun, Tinggui Wang +2
We report the discovery of large-amplitude mid-infrared variabilities (MIR; mag) in the Wide-field Infrared Survey Explorer W1 and W2 bands of the low-luminosity narrow-…
Piercing Through Highly Obscured and Compton-thick AGNs in the Chandra Deep Fields: I. X-ray Spectral and Long-term Variability Analyses
Junyao Li, Yongquan Xue, Mouyuan Sun +13
We present a detailed X-ray spectral analysis of 1152 AGNs selected in the Chandra Deep Fields (CDFs), in order to identify highly obscured AGNs (…
Thick-disc model to explain the spectral state transition in NGC 247
Jing Guo, Mouyuan Sun, Wei-Min Gu +1
We propose the thick-disc model of Gu et al. 2016 to interpret the transition between soft ultraluminous state (SUL) and supersoft ultraluminous (SSUL) state in NGC 247. As accreti…
