Vigorous turbulence driven by quasar-mode feedback in a cluster core
Satoshi Yamada, Shutaro Ueda, Hirofumi Noda +9
Quasars are among the most luminous objects. They are powered by accretion onto supermassive black holes. They are thought to impact cosmological evolution primarily through energe…
Unification models of Active Galactic Nuclei
Claudio Ricci
This chapter presents an overview of the unification models for Active Galactic Nuclei (AGN), focusing on the physical structures, classification schemes, and evolutionary processe…
Correlation Between Hard X-Ray and Cosmic Neutrino Sources: From Obscured AGN to Blazars
Emma Kun, Imre Bartos, Claudio Ricci +5
The origin of high-energy astrophysical neutrinos remains a key open question in multimessenger astrophysics. A correlation between unabsorbed hard X-ray and high-energy neutrino l…
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 Ga…
The study of the circumnuclear environment of accreting supermassive black holes with realistic X-ray spectral models
Georgios Dimopoulos, Claudio Ricci, Stéphane Paltani
X-ray spectral modeling is a powerful tool for studying the immediate environment of accreting objects, including supermassive black holes. Several models, either phenomenological…
A XRISM Study of Highly Ionized Iron Emission Lines from the Low-Eddington-ratio AGN in NGC 7213
Kaito Murakami, Taiki Kawamuro, Ryota Tomaru +10
We present an analysis of XRISM and NuSTAR data obtained for the nearby low-Eddington active galactic nucleus NGC 7213. Our goal is to examine whether its He-like and H-like iron e…
UGC 2369S: a Kpc Scale Triple Merger Candidate Identified in a Nearby Luminous Infrared Galaxy
Yuanze Ding, Michael J. Koss, Fiona A. Harrison +12
We present high spatial resolution (1.0''), multi-wavelength observations of UGC 2369S, a nearby luminous infrared galaxy showing three distinct cores separated on kpc sc…
The X-ray weakness of Little Red Dots and JWST-selected AGN: comparison with local AGN in different accretion regimes
A. Tortosa, C. Ricci, P. Du +5
We investigate the origin of the observed X-ray weakness in high z LRDs and other JWST-selected broad line AGN by comparing their X-ray and optical properties with those of a diver…
