Compton-thick AGN in the NuSTAR era III: A systematic study of the torus covering factor
Stefano Marchesi, Marco Ajello, Xiurui Zhao +9
We present the analysis of a sample of 35 candidate Compton thick (CT-) active galactic nuclei (AGNs) selected in the nearby Universe (average redshift <z>~0.03) with the Swift-BAT…
NuSTAR reveals that the heavily obscured nucleus of NGC 2785 was the contaminant of IRAS 09104+4109 in the BeppoSAX/PDS hard X-rays
C. Vignali, P. Severgnini, E. Piconcelli +7
The search for heavily obscured active galactic nuclei (AGNs) has been revitalized in the last five years by NuSTAR, which has provided a good census and spectral characterization…
SUPER I. Toward an unbiased study of ionized outflows in z~2 active galactic nuclei: survey overview and sample characterization
C. Circosta, V. Mainieri, P. Padovani +36
Theoretical models of galaxy formation suggest that the presence of an active galactic nucleus (AGN) is required to regulate the growth of its host galaxy through feedback mechanis…
The hyperluminous Compton-thick quasar nucleus of the hot DOG W1835+4355 observed by NuSTAR
L. Zappacosta, E. Piconcelli, F. Duras +11
We present a 155ks NuSTAR observation of the hot dust-obscured galaxy (hot DOG) W1835+4355. We extracted spectra from the two NuSTAR detectors and analyzed them jointly wi…
The molecular gas content in obscured AGN at z > 1
M. Perna, M. T. Sargent, M. Brusa +11
The standard AGN-galaxy co-evolutionary scenario predicts a phase of deeply buried supermassive black hole growth coexisting with a starburst (SB) before feedback phenomena deplete…
The Chandra COSMOS Legacy Survey: Compton Thick AGN at high redshift
G. Lanzuisi, F. Civano, S. Marchesi +8
The existence of a large population of Compton thick (CT, ) AGN is a key ingredient of most Cosmic X-ray background synthesis models. However, direct identif…
The 500 ks Chandra observation of the z = 6.31 QSO SDSS J1030+0524
R. Nanni, R. Gilli, C. Vignali +23
We present the results from a ks Chandra observation of the QSO SDSS J1030+0524. This is the deepest X-ray observation to date of a QSO. The QSO is dete…
Molecular outflow and feedback in the obscured Quasar XID2028 revealed by ALMA
M. Brusa, G. Cresci, E. Daddi +29
We imaged with ALMA and ARGOS/LUCI the molecular gas and the dust and stellar continuum in XID2028, an obscured QSO at z=1.593, where the presence of a massive outflow in the ioniz…
Yet another UFO in the X-ray spectrum of a high-z lensed QSO
M. Dadina, C. Vignali, M. Cappi +6
Ultra-fast outflows (UFO) appear to be common in local active galactic nuclei (AGN) and may be powerful enough (1\% of L) to effectively quench the sta…
The NuSTAR Extragalactic Surveys: X-ray spectroscopic analysis of the bright hard-band selected sample
L. Zappacosta, A. Comastri, F. Civano +23
We discuss the spectral analysis of a sample of 63 Active Galactic Nuclei (AGN) detected above a limiting flux of keV erg/s/cm in the multi-tiered N…
Compton thick AGN in the NuSTAR era
Stefano Marchesi, Marco Ajello, Lea Marcotulli +3
We present the 2-100 keV spectral analysis of 30 candidate Compton thick (CT-) active galactic nuclei (AGN) selected in the Swift-BAT 100-month survey. The average redshift of thes…
