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

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…

PDRs4All: XVIII. The evolution of the PAH ionisation and PAH size distribution across the Orion Bar

Alexandros Maragkoudakis, Christiaan Boersma, Els Peeters +25

We investigate the evolution of the PAH population's charge state and size across key physical zones in the Orion Bar, which include the HII region, the atomic PDR (APDR), and thre…

Breathless BEARS: [O $_{III}$ ] 88 $μ$ m Emission of Dusty Star-Forming Galaxies at $z = 3 - 4$

T. J. L. C. Bakx, Hiddo S. B. Algera, Prachi Prajapati +13

We present [O $_{III}$ ] 88 $μ$ m observations towards four $Herschel$ -selected dusty star-forming galaxies (DSFGs; log $_{10}$ $μ$ L $_{IR}$ /L $_{⊙}$ = 13.5 - 14 at $z…

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…

SPHEREx: Aromatics, Aliphatics and PAH Size across the Iris Nebula

Christiaan Boersma, Alexandros Maragkoudakis, Louis J. Allamandola +4

Observations by the SpectroPhotometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) are combined with Spitzer spectral map data to study the a…

Multiphase gas offsets in the atmospheres of central galaxies and their consequences for SMBH activation I. The hot and warm ionized gas phases

Francesco Ubertosi, Fabrizio Brighenti, Ewan O'Sullivan +10

We investigate the spatial relationships between multi-phase gas components and supermassive black hole (SMBH) activity in a sample of 25 cool core galaxy groups and clusters. Usin…

JVLA and VLBA study of the merging cool core CHIPS 1911+4455 at z~0.5: radio emission from an infant AGN and from a rapidly star-forming BCG

Francesco Ubertosi, Myriam Gitti, Pasquale Temi +5

Recent studies of galaxy clusters found peculiar cases at the boundary between non-cool core and cool core systems. While unusual, these objects can help us understand the evolutio…

Truncations in the X-ray Halos of Early-Type Galaxies as a Tracer of Feedback and Mergers

Nushkia Chamba, Pamela M. Marcum, Alejandro S. Borlaff +2

The morphology of X-ray halos in early-type galaxies depends on key structure assembly processes such as feedback and mergers. However, the signatures of these processes are diffic…

The dust emissivity index beta in infrared-bright galaxies at 1.5 < z < 4.2

G. J. Bendo, T. J. L. C. Bakx, H. S. B. Algera +16

We have measured the dust emissivity index beta for 21 infrared-bright sources (including several gravitationally lensed galaxies) at 1.5 < z < 4.2 using Atacama Large Millimeter/s…
