Time-evolving Diagnostic of the Ionized Absorbers in NGC 4051. II. High-throughput Time-resolved Spectroscopy
Alfredo Luminari, Fabrizio Nicastro, Roberto Serafinelli +5
Active Galactic Nuclei (AGNs) are one of the most powerful sources in the Universe. The accretion-liberated energy can strongly impact the surrounding environment, up to the host g…
A new era for Dual AGN science with SHARP
P. Severgnini, C. Vignali, A. De Rosa +21
The search for and the characterization of ultra-compact dual active galactic nuclei (AGN) are among the hottest topics of current extragalactic astrophysics. These systems involve…
The Millimeter/X-ray Relation in Rapidly Accreting Supermassive Black Holes at
Sophie M. Venselaar, Claudio Ricci, Santiago Del Palacio +12
A tight correlation between nuclear millimeter and X-ray emission has recently been found in nearby () and low-Eddington ratio () radio-quiet Active G…
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…
