SMBH binary candidate PKS J2134-0153: Possible multi-band periodic variability and inter-band time lags
Guowei Ren, Mouyuan Sun, Nan Ding +2
Studying the periodic flux-variation behavior of blazars is vital for probing supermassive black hole binaries and the kinematics of relativistic jets. In this work, we report the…
The disk reverberation mapping of the lensed quasar Q0957+561
Marcin Marculewicz, Mouyuan Sun, Zhixiang Zhang +1
The measurement of continuum time lags in lensed quasars can effectively probe the accretion physics of quasars. This is because microlensing observations of lensed quasars can pro…
Newly Discovered Changing-look Active Galactic Nuclei from SDSS and LAMOST Surveys
Qian Dong, Zhi-Xiang Zhang, Wei-Min Gu +2
Changing-look Active Galactic Nuclei (CL AGNs) exhibit drastic variations in broad emission lines (BELs), the mechanism of which remains unclear. Expanding the sample of CL AGNs is…
Two Dynamically Discovered Compact Object Candidate Binary Systems from LAMOST Low-resolution Survey
Senyu Qi, Wei-Min Gu, Zhi-Xiang Zhang +3
We report two binary systems, LAMOST J035540+381550 (hereafter J035540) and LAMOST J035916+400732 (hereafter J035916), identified through the Large Sky Area Multi-Object Fiber Spec…
A Sample of Compact Object Candidates in Single-lined Spectroscopic Binaries from LAMOST Medium Resolution Survey
Hao-Bin Liu, Wei-Min Gu, Zhi-Xiang Zhang +3
The stellar spectra from LAMOST Medium Resolution Survey can be used to search for compact objects in binaries. The LAMOST DR10 catalog includes > 980, 000 targets with multiple me…
A reverberation mapping study of a highly variable AGN 6dFGS gJ022550.0-060145
Danyang Li, Mouyuan Sun, Junfeng Wang +2
We use LCOGT observations (MJD ) with a total exposure time of hours and a median cadence of days to measure the inter-band time delays (with respect…
The hidden companion in J1527: a 0.69 solar-mass white dwarf?
Zhi-Xiang Zhang, Hao-Bin Liu, Tuan Yi +2
Finding nearby neutron stars can probe the supernova and metal-enrichment histories near our Solar system. Recently, Lin et al. 2023 reported an exciting neutron star candidate, 2M…
