The BAT AGN Spectroscopic Survey -- XVIII. Searching for Supermassive Black Hole Binaries in the X-rays
Tingting Liu, Michael Koss, Laura Blecha +15
Theory predicts that a supermassive black hole binary (SMBHB) could be observed as a luminous active galactic nucleus (AGN) that periodically varies on the order of its orbital tim…
Did ASAS-SN Kill the Supermassive Black Hole Binary Candidate PG1302-102?
Tingting Liu, Suvi Gezari, M. Coleman Miller
Graham et al. (2015a) reported a periodically varying quasar and supermassive black hole binary candidate, PG1302-102 (hereafter PG1302), which was discovered in the Catalina Real-…
A Multi-wavelength Analysis of Binary-AGN Candidate PSO J334.2028+01.4075
Adi Foord, Kayhan Gultekin, Mark Reynolds +4
We present analysis of the first Chandra observation of PSO J334.2028+01.4075 (PSO J334), targeted as a binary-AGN candidate based on periodic variations of the optical flux. With…
A Periodically Varying Luminous Quasar at z=2 from the Pan-STARRS1 Medium Deep Survey: A Candidate Supermassive Black Hole Binary in the Gravitational Wave-Driven Regime
Tingting Liu, Suvi Gezari, Sebastien Heinis +11
Supermassive black hole binaries (SMBHBs) should be an inevitable consequence of the hierarchical growth of massive galaxies through mergers, and the strongest sirens of gravitatio…
