AGN in overdense environments at high- with AXIS
Fabio Vito, Paolo Tozzi, Roberto Gilli +3
Overdense regions at high redshift () are perfect laboratories to study the relations between environment and SMBH growth, and the AGN feedback processes on the surrou…
Surveying the onset and evolution of supermassive black holes at high-z with AXIS
Nico Cappelluti, Adi Foord, Stefano Marchesi +8
The nature and origin of supermassive black holes (SMBHs) remain an open matter of debate within the scientific community. While various theoretical scenarios have been proposed, e…
Are there more galaxies than we see around high- quasars?
Tommaso Zana, Stefano Carniani, David Prelogović +5
Whether or not quasars lie in the most massive dark-matter halos of the Universe is still a subject of dispute. While most theoretical studies support this scenario,…
X-ray properties and obscured fraction of AGN in the J1030 Chandra field
Matilde Signorini, Stefano Marchesi, Roberto Gilli +13
The 500ks Chandra ACIS-I observation of the field around the quasar SDSS J1030+0524 is currently the 5th deepest extragalactic X-ray survey. The rich multi-band coverage o…
Probing massive black holes with gravitational waves
Srija Chakraborty, Simona Gallerani, Tommaso Zana +6
We investigate the coalescence of massive black hole () binaries (MBHBs) at by adopting a suite of cosmological hydrodynamical simu…
Large-scale clustering of buried X-ray AGN: Trends in AGN obscuration and redshift evolution
Akke Viitanen, Viola Allevato, Alexis Finoguenov +4
In order to test active galactic nucleus (AGN) unification and evolutionary models, we measured the AGN clustering properties as a function of AGN obscuration defined in terms of h…
The Most Obscured AGNs in the XMM-SERVS Fields
Wei Yan, W. N. Brandt, Fan Zou +9
We perform X-ray spectral analyses to derive characteristics (e.g., column density, X-ray luminosity) of 10,200 active galactic nuclei (AGNs) in the XMM-Spitzer Extragalac…
LBT-MODS spectroscopy of high-redshift candidates in the Chandra J1030 field. A newly discovered z2.8 large scale structure
Stefano Marchesi, Marco Mignoli, Roberto Gilli +13
We present the results of a spectroscopic campaign with the Multi-Object Double Spectrograph (MODS) instrument mounted on the Large Binocular Telescope (LBT), aimed at obtaining a…
X-ray Unveiling Events in a z~1.6 Active Galactic Nucleus in the 7 Ms Chandra Deep Field-South
Li-Ming Yu, Bin Luo, William N. Brandt +14
We investigate the extreme X-ray variability of a z = 1.608 active galactic nucleus in the 7 Ms Chandra Deep Field-South (XID 403), which showed two significant X-ray brightening e…
AGN feedback in an infant galaxy cluster: the LOFAR-Chandra view of the giant FRII radio galaxy J103025+052430 at z=1.7
M. Brienza, R. Gilli, I. Prandoni +19
In the nearby universe jets from AGN are observed to have a dramatic impact on their surrounding extragalactic environment. Their effect at the `cosmic noon' (z>1.5), the epoch whe…
The universal shape of the X-ray variability power spectrum of AGN up to
M. Paolillo, I. E. Papadakis, W. N. Brandt +12
We study the ensemble X-ray variability properties of Active Galactic Nuclei (AGN) over a large range of timescales (20 ks 14 yrs), redshift (), lu…
