The formation of supermassive black holes from Population III.1 seeds. IV. Self-regulated seeding from supermassive star ionizing feedback

Maya A. Petkova, Jonathan C. Tan, Jasbir Singh +5

Supermassive Population III.1 stars, i.e., formed from pristine, metal-free gas leading to conditions where dark matter annihilation heating is significant, have been proposed as t…

BlackHoleWeather -- Jet-regulated chaotic cold accretion across the meso scale: Variability and kinematics

Vieri Cammelli, Massimo Gaspari, Filippo Barbani +10

Chaotic cold accretion (CCA) predicts that supermassive black holes are fed by multiphase clouds condensing from turbulent hot atmospheres. In jet-regulated systems cold gas must a…

BlackHoleWeather -- Spin-coupled chaotic cold accretion across the meso scale: Variability and kinematics

Olmo Piana, Massimo Gaspari, Vieri Cammelli +10

Supermassive black hole (SMBH) spin records the vector history of accretion. In chaotic cold accretion (CCA), this history is set by clouds and filaments whose torques can add cohe…

BlackHoleWeather -- Chaotic cold accretion across the meso-scale: Morphology and thermodynamics

Filippo Barbani, Massimo Gaspari, Vieri Cammelli +12

Supermassive black holes (SMBHs) self-regulate galaxies, groups, and clusters, yet the pathway transporting gas from halo scales to sub-pc radii remains debated. In hot stratified…

BlackHoleWeather -- Chaotic cold accretion across the meso-scale: Variability and kinematics

Filippo Barbani, Massimo Gaspari, Olmo Piana +12

Accretion onto supermassive black holes (SMBHs) in realistic halos is time-variable, governed by turbulence, cooling, and multiphase condensation. In chaotic cold accretion (CCA),…

BlackHoleWeather -- Jet-regulated chaotic cold accretion across the meso scale: Morphology and thermodynamics

Vieri Cammelli, Massimo Gaspari, Olmo Piana +11

How mechanical AGN feedback couples to multiphase condensation across scales remains a problem in galaxy groups and clusters. It is unclear how jets reshape the chaotic cold accret…
