A Population Study for Searching Supermassive Binary Black Holes in Active Galactic Nuclei: Continuum Spectral Features and Periodic Variabilities
Zekun Li, Changshuo Yan, Youjun Lu
Active sub-pc supermassive binary black holes (SMBBHs) are expected to exhibit various electromagnetic signatures due to unique dynamical and geometric structures of their accretio…
An equal mass ratio supermassive binary black holes in Q J0158-4325 with periodic microlensing signature?
Changshuo Yan, Youjun Lu, Junqian Ge +1
This study aims to test whether a supermassive binary black hole (SMBBH) system with a triple-disk accretion structure can explain the observed 173-day periodic microlensing…
Multiwavelength periodic microlensing signatures of macrolensed supermassive binary black holes
Changshuo Yan, Youjun Lu
The microlensing of lensed quasars presents a promising avenue for understanding the structure of accretion disks around supermassive binary black holes (SMBBHs). We investigated t…
Gravitational Lensing of Gravitational Waves from Astrophysical Sources: Theory, Detection, and Applications
Zhiwei Chen, Youjun Lu
Gravitational waves (GWs) from distant sources such as inspiralling and merging stellar-mass compact binaries, intermediate-mass and supermassive-binary-black-hole can be gravitati…
