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
