Electromagnetic Signatures of Supermassive Binary Black Holes: Synchrotron, Self-Lensing Flares, and Jet Precession
Hong-Xuan Jiang, Xinyu Li, Jing-Ze Xia +3
The recent evidence for a nanohertz gravitational wave background from Pulsar Timing Arrays highlights the urgent need to identify electromagnetic counterparts to supermassive bina…
Tidal Heating of Stellar Clusters in Fuzzy Dark Matter Halos
Yiheng Liu, Xinyu Li
Ultra-faint dwarf galaxies serve as powerful testing grounds for wave dark matter models through dynamical stellar heating. Previous simulation-based work derived a lower bound on…
Black Hole Collisions With Thin Accretion Disks: OJ 287 and Small-Mass-Ratio Supermassive Black Hole Binary Candidates
Sean M. Ressler, Luciano Combi, Bart Ripperda +1
OJ 287 is the best-known supermassive black hole binary candidate in the nanohertz gravitational wave band. It exhibits periodic flares every 12 years, likely caused by coll…
A Promise for the JWST era: Massive black holes directly collapsed from wave dark matter haloes, and Star formation in and around their accretion flows
Xiaobo Dong, Yongda Zhu, Marcia Rieke +7
There are several puzzling phenomena from recent JWST observations, which seem to push the standard ÎCDM cosmology over the edge. All those puzzles can be understood in a coherent…
