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…
BlackHoleWeather -- Spin-coupled chaotic cold accretion across the meso-scale: Morphology and thermodynamics
Olmo Piana, Massimo Gaspari, Filippo Barbani +10
Supermassive black hole (SMBH) spin is a key but poorly constrained ingredient of the feeding-feedback loop. Chaotic cold accretion (CCA) of cold gas clouds delivers rapidly varyin…
