A Possible Triple Formation Scenario of Binary Black Hole Merge With One In Pair-instability Supernova Mass Gap
Tian Huang, Xizhen Lu, Guoliang Lü +8
Observations of binary black hole (BBH) mergers detected by LIGO -- such as GW170729, GW190620, GW190706, GW230107, GW230820, and GW230928 -- feature high effective spins and prima…
Discovery of Repeating Transitions in 16 Changing-look Active Galactic Nuclei
Qian Dong, Zhi-Xiang Zhang, Wei-Min Gu +5
The repeating changing-look active galactic nuclei (RCL AGNs) exhibit multiple appearances and disappearances of broad emission lines (BELs), whose underlying mechanism remains a p…
Hunting for Compact Object Binaries from eRASS1 Optical Counterparts through ZTF Time-domain Photometry and Multi-wavelength Census
Xin-Yu Fang, Hao-Bin Liu, Wei-Min Gu
Capitalizing on the eRASS1 optical counterpart catalog, we conduct a systematic census of compact object binary (COB) candidates, with a primary focus on X-ray binaries (XRBs), by…
The Evolution of Cataclysmic Variables Under Various Magnetic Braking Prescriptions
Wen-Shi Tang, Xiang-Dong Li, Zhe Cui +2
Recent studies revealed discrepancies between observations and the predictions of the standard magnetic braking (MB). Although alternative models have been broadly discussed in neu…
Probing Compact Objects in Wide-Orbit Binaries with Joint LAMOST LRS and MRS
Hao-Bin Liu, Wei-Min Gu
Wide-orbit binaries serve as crucial laboratories for understanding stellar evolution and identifying quiescent compact objects. In this work, we search for compact objects in wide…
SED and Galactic kinematic diagnostics for dormant BH/NS binary candidates
Qian-Yu An, Wei-Min Gu
The third data release of the Gaia mission (Gaia DR3) has enabled large-scale searches for dormant black hole and neutron star binaries with stellar companions at AU-scale separati…
