Exploring the AGN population in protoclusters: results from the TNG300 simulation and comparison with observations

A. Traina, F. Vito, A. Pillepich +7

In this work, we investigate the physical properties and cosmic evolution of galaxies and AGN in a sample of 280 protoclusters identified in the TNG300 simulation, selected to end…

The birth of the intracluster medium: the evolution of multiphase gas and Lyman- haloes in a simulated protocluster

Jake S. Bennett, Aaron Smith, Fabrizio Arrigoni-Battaia +3

Galactic haloes host a complex, multiphase circumgalactic medium (CGM), and at high redshift are fed by cold, filamentary inflows. In contrast, mature galaxy clusters are dominated…

The imprint of AGN-driven outflows on the CGM: the case of Lyα nebulae around high-z quasars

Silvia C. Rueda-Vargas, Vincenzo Mainieri, Giulia Tozzi +5

Some cosmological hydrodynamical simulations predict that outflows driven by active galactic nuclei (AGN) play a key role in powering the Ly nebulae observed around high-redshif…

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…

The properties of X-ray selected AGN in protoclusters pinpointed by Enormous Lya Nebulae

A. Traina, F. Vito, F. Arrigoni-Battaia +11

Protoclusters of galaxies are overdense regions of the Universe characterized by large gas reservoirs. Such environments make them perfect laboratories to investigate galaxy-AGN co…

The MUSE Ultra Deep Field (MUDF) VII. Probing high-redshift gas structures in the surroundings of ALMA-identified massive dusty galaxies

A. Pensabene, M. Galbiati, M. Fumagalli +12

We present new ALMA continuum and spectral observations of the MUSE Ultra Deep Field (MUDF), a arcmin region with ultradeep multiwavelength imaging and spectroscopy…
