The first extragalactic ultra-compact X-ray binary : a candidate black hole-white dwarf system
Qian-Qi Ma, Jiachang Zhang, Wei-Min Gu +3
M31 UCXB-1 is one of the brightest X-ray point sources in the bulge of M31, with a peak X-ray luminosity $ L_{\mathrm{0.5-10 \: keV}} = 2.9^{+0.2}_{-0.2} \times 10^{38} \: \mathrm{…
A Study of Cataclysmic Variables from the eFEDS Survey
Rui Wang, Wei-Min Gu, Zhi-Xiang Zhang +3
We present 17 cataclysmic variables (CVs) obtained from the crossmatch between the Sloan Digital Sky Survey (SDSS) and eROSITA Final Equatorial Depth Survey (eFEDS), including 8 kn…
Explanation of the Mass Distribution of Binary Black Hole Mergers
Lei Li, Guoliang Lv, Chunhua Zhu +5
Gravitational wave detectors are observing an increasing number of binary black hole (BBH) mergers, revealing a bimodal mass distribution of BBHs, which hints at diverse formation…
A Be star-black hole binary with a wide orbit from LAMOST time-domain survey
Qian-Yu An, Yang Huang, Wei-Min Gu +21
Binary systems consisting of an early type star and a black hole (BH) are crucial for understanding various astrophysical phenomena, particularly the origins of detected gravitatio…
Searching for Accreting Compact Object Binaries in SRG/eROSITA eRASS1
Hao-Bin Liu, Wei-Min Gu, Yongqi Lu +2
Compact object binaries with accreting white dwarfs, neutron stars, or black holes are crucial for understanding accretion physics. In this study, we identify accreting compact obj…
A Sandwich Model for Changing-Look AGNs
Qian-Qi Ma, Wei-Min Gu, Zhen-Yi Cai +4
The spectral variability of changing-look active galactic nuclei (CL-AGNs) occurred on timescales of years to tens of years, posing a significant challenge to the standard thin dis…
