Constraining AGN accretion physics with black hole mass-luminosity scaling relations

F. Fiore, M. Gaspari, S. Puccetti +3

We test how supermassive black holes are fed by combining new black hole mass-luminosity relations with physically motivated feeding models. We build a uniform sample of 1729 unobs…

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…

HST view of NGC 5044: Constraints on Filament Widths, Magnetic Support, Multiphase Structure, and Comparison with Cluster Environments

Prathamesh Tamhane, Ming Sun, William Waldron +12

We present new Hubble Space Telescope (HST) imaging of ionised filaments in the brightest group galaxy NGC 5044. These filaments extend several kiloparsecs and have widths of $\sim…

AGN Feedback and the Development of Dusty Multiphase Gas in X-ray Emitting Elliptical Galaxies

Pasquale Temi, Francesco Ubertosi, Fabrizio Brighenti +9

This paper investigates the physical and kinematic properties of dust-rich regions in a small sample of group-centered elliptical galaxies, emphasizing their connection with the ho…

Dissecting the turbulent weather driven by mechanical AGN feedback

D. Wittor, M. Gaspari

Turbulence in the intracluster, intragroup, and circumgalactic medium plays a crucial role in the self-regulated feeding and feedback loop of central supermassive black holes. We d…

A molecular absorption line survey toward the AGN of Hydra-A

Tom Rose, A. C. Edge, F. Combes +16

We present Atacama Large Millimeter/submillimeter Array observations of the brightest cluster galaxy Hydra-A, a nearby () giant elliptical galaxy with powerful and extende…

Anatomy of a Cooling Flow: The Feedback Response to Pure Cooling in the Core of the Phoenix Cluster

M. McDonald, B. R. McNamara, G. M. Voit +17

We present new, deep observations of the Phoenix cluster from the Chandra X-ray Observatory, the Hubble Space Telescope, and the Karl Jansky Very Large Array. These data provide an…

Circumgalactic Gas and the Precipitation Limit

G. M. Voit, A. Babul, Iu. Babyk +15

During the last decade, numerous and varied observations, along with increasingly sophisticated numerical simulations, have awakened astronomers to the central role the circumgalac…
