Low-power jet-ISM coupling and disk-plane perturbations in the edge-on Seyfert galaxy NGC 4388

M. Ceci, G. Venturi, C. Marconcini +26

Active galactic nuclei (AGN) may regulate galaxy evolution through radiatively driven winds and collimated jets, but their relative impact and coupling to the interstellar medium (…

The Multiphase CGM in the Epoch of Reionization: CII and CIV absorbers around [OIII] Emitters

C. Piscitelli, V. D'Odorico, M. Galbiati +17

We investigate the multiphase circumgalactic medium (CGM) during the Epoch of Reionization (EoR, ) by cross-correlating cool- CII and warm-ionized CIV absorption systems with…

Precision near-IR spectroscopy for understanding AGN physics and shed light on the H0 tension -- SHARP Science Book

M. Signorini, V. N. Bennert, E. Dalla Bontà +3

The persistent tension between early- and late-Universe measurements of the Hubble constant (H0) remains on of the most significant challenges in modern cosmology. The Spectroastro…

Enhanced activity in close dual-AGN systems in the local Universe

Lorenzo Battistini, Alessandra De Rosa, Paola Severgnini +16

We present the study of an X-ray selected sample of active galactic nuclei (AGN) in pairs at projected spatial separations 1 </kpc < 100 at z < 0.1, using XMM-Newton and Chan…

Supermassive Black Hole Winds in X-rays: SUBWAYS IV. Tracing Radio Emission and Unveiling the Role of Winds

E. Amenta, M. Brienza, G. Bruni +30

Most Active Galactic Nuclei (AGN) are Radio Quiet, with radio emission that may arise from star-formation activity, AGN-driven winds, weak jets, and coronal activity. Disentangling…

Supermassive Black Hole Winds in X-rays: SUBWAYS V. Properties of hot coronae in quasars at intermediate redshift

S. Peluso, G. Lanzuisi, A. Comastri +25

We present the X-ray analysis of coronal properties in a statistically representative sample of 23 mostly radio-quiet AGN from the SUBWAYS campaign (SUpermassive Black holes Winds…

A deep X-ray look to the most obscured quasar at z~3.6 and its environment

I. Villani, L. Zappacosta, E. Piconcelli +17

The most luminous and obscured quasars (QSOs) detected in infrared all-sky surveys could represent a key co-evolutionary phase from nuclear to circum-galactic (CG) scales in the fo…

Intervening nuclear obscuration changing the X-ray look of the QSO CFHQS J164121+375520

Fabio Vito, William Nielsen Brandt, Andrea Comastri +16

X-ray observations of the optically selected QSO CFHQS J164121+375520 (hereafter J1641) revealed that its flux dropped by a factor from 2018, when it was a bri…

The WISSH quasars project XI. The mean Spectral Energy Distribution and Bolometric Corrections of the most luminous quasars

Ivano Saccheo, Angela Bongiorno, Enrico Piconcelli +18

Hyper-luminous Quasi-Stellar Objects (QSOs) represent the ideal laboratory to investigate Active Galactic Nuclei (AGN) feedback mechanism since their formidable energy release caus…
