Toward Black Hole Stars: supermassive black hole growth in nuclear clusters via stellar-object and gas accretion
Konstantinos Kritos, Joseph Silk
Supermassive black hole (SMBH) growth plausibly occurs via runaway astrophysical black hole mergers in nuclear star clusters that form intermediate mass black hole seeds at high re…
From nuclear star clusters to Little Red Dots: black hole growth, mergers, and tidal disruptions
Konstantinos Kritos, Joseph Silk
Little Red Dots, discovered by the James Webb Space Telescope, are hypothesized to be active galactic nuclei containing a supermassive black hole, possibly surrounded by a dense st…
Supermassive black holes from runaway mergers and accretion in nuclear star clusters
Konstantinos Kritos, Emanuele Berti, Joseph Silk
Rapid formation of supermassive black holes occurs in dense nuclear star clusters that are initially gas-dominated. Stellar-mass black hole remnants of the most massive cluster sin…
Effects of Superradiance in Active Galactic Nuclei
Priyanka Sarmah, Himanshu Verma, Kingman Cheung +1
A supermassive black hole (SMBH) at the core of an active galactic nucleus (AGN) provides room for the elusive ultra-light scalar particles (ULSP) to be produced through a phenomen…
