X-ray redshifts for obscured AGN: a case study in the J1030 deep field
Alessandro Peca, Cristian Vignali, Roberto Gilli +9
We present a procedure to constrain the redshifts of obscured ( cm) Active Galactic Nuclei (AGN) based on low-count statistics X-ray spectra, which can be ado…
X-ray properties of dust-obscured galaxies with broad optical/UV emission lines
Fan Zou, William N. Brandt, Fabio Vito +4
Dust-obscured galaxies (DOGs) with extreme infrared luminosities may represent a key phase in the co-evolution of galaxies and supermassive black holes. We select 12 DOGs at $0.3\l…
The web of the Giant: spectroscopic confirmation of a Large Scale Structure around the z=6.31 quasar SDSS J1030+0524
Marco Mignoli, Roberto Gilli, Roberto Decarli +14
We report on the spectroscopic confirmation of a large scale structure around the luminous, z=6.31 QSO SDSS~J1030+0524, that is powered by a billion solar mass black hole. The stru…
Chandra reveals a luminous Compton-thick QSO powering a blob in a starbursting protocluster
Fabio Vito, William Nielsen Brandt, Bret Darby Lehmer +7
Galaxy clusters in the local universe descend from high-redshift overdense regions known as protoclusters. The large gas reservoirs and high rate of galaxy interaction in protoclus…
Mock catalogs for the extragalactic X-ray sky: simulating AGN surveys with Athena and with the AXIS probe
Stefano Marchesi, Roberto Gilli, Giorgio Lanzuisi +8
We present a series of new, publicly available mock catalogs of X-ray selected active galactic nuclei (AGNs), non-active galaxies, and clusters of galaxies. They are based on up-to…
Piercing through Highly Obscured and Compton-thick AGNs in the Chandra Deep Fields. II. Are Highly Obscured AGNs the Missing Link in the Merger-Triggered AGN-Galaxy Coevolution Models?
Junyao Li, Yongquan Xue, Mouyuan Sun +12
By using a large highly obscured () AGN sample (294 sources at ) selected from detailed X-ray spectral analyses in the deepest Chandra…
The deep Chandra survey in the SDSS J1030+0524 field
R. Nanni, R. Gilli, C. Vignali +18
We present the X-ray source catalog for the 479 ks Chandra exposure of the SDSS J1030+0524 field, that is centered on a region that shows the best evidence to date of an overdensit…
Dust and gas content of high-redshift galaxies hosting obscured AGN in the CDF-S
Q. D'Amato, R. Gilli, C. Vignali +14
Obscured AGN represent a significant fraction of the entire AGN population, especially at high redshift (~70% at z=3--5). They are often characterized by the presence of large gas…
The evolving AGN duty cycle in galaxies since z3 as encoded in the X-ray luminosity function
I. Delvecchio, E. Daddi, J. Aird +10
We present a new modeling of the X-ray luminosity function (XLF) of Active Galactic Nuclei (AGN) out to z3, dissecting the contribution of main-sequence (MS) and starburst (S…
A Large Population of Obscured AGN in Disguise as Low Luminosity AGN in Chandra Deep Field South
Erini Lambrides, Marco Chiaberge, Timothy Heckman +3
Population synthesis models of actively accreting super-massive black holes (or active galactic nuclei -- AGN) predict a large fraction that must grow behind dense, obscuring scree…
An Extreme X-ray Variability Event of a Weak-Line Quasar
Qingling Ni, W. N. Brandt, W. Yi +8
We report the discovery of an extreme X-ray flux rise (by a factor of > 20) of the weak-line quasar SDSS J153913.47+395423.4 (hereafter SDSS J1539+3954) at z = 1.935. SDSS J1539+39…
