We present JWST/NIRSpec IFU spectroscopy of the central pc () of NGC 4696, the BCG in the Centaurus cluster. Leveraging the (…
JWST reveals how black holes are fed: kiloparsec-scale multiphase filaments feed sub-kiloparsec circumnuclear disks
Julie Hlavacek-Larrondo, Hyunseop Choi, Minghao Guo +35
The Centaurus cluster is one of the most important archetypes of radio-mode AGN feedback, with its central galaxy, NGC 4696, launching powerful jets that inflate X-ray cavities and…
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…
AGN Feedback and the Development of Dusty Multiphase Gas in X-ray Emitting Elliptical Galaxies

We present a comprehensive kinematic and ionization analysis of the warm ionized filaments ( K) in M87, the central galaxy of the Virgo cluster, using new integral field spec…
The relationship between warm and hot gas-phase metallicity in massive elliptical galaxies and the influence of AGN feedback
Valeria Olivares, Yuanyuan Su, Pasquale Temi +10
Warm ionized gas is ubiquitous at the centers of X-ray bright elliptical galaxies. While it is believed to play a key role in the feeding and feedback processes of supermassive bla…

Massive galaxies in cooling flow clusters display clear evidence of feedback from Active Galactic Nuclei (AGN). Joint X-ray and radio observations have shown that AGN radio jets pu…
A hot core in the group-dominant elliptical galaxy NGC 777
Ewan O'Sullivan, Kamlesh Rajpurohit, Gerrit Schellenberger +8
NGC 777 provides an example of a phenomenon observed in some group-central ellipticals, in which the temperature profile shows a central peak, despite the short central cooling tim…
