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…
Compton-thick AGN in the NuSTAR era IV: A deep NuSTAR and XMM-Newton view of the candidate Compton thick AGN in ESO 116-G018
X. Zhao, S. Marchesi, M. Ajello
We present the 2--78 keV spectral analysis of the deep NuSTAR and XMM-Newton observation of a nearby Seyfert 2 galaxy, ESO 116-G018, which is selected as a candidate Compton-thick…
Compton-thick AGN in the NuSTAR era II: A deep NuSTAR and XMM-Newton view of the candidate Compton thick AGN in NGC 1358
X. Zhao, S. Marchesi, M. Ajello +4
We present the combined NuSTATR and XMM-Newton 0.6-79 keV spectral analysis of a Seyfert 2 galaxy, NGC 1358, which we selected as a candidate Compton thick (CT-) active galactic nu…
2FHL J0826.1-4500: Discovery of a possible shock-cloud interaction on the Western edge of the Vela SNR
Jordan Eagle, Stefano Marchesi, Daniel Castro +3
We report on the investigation of a very high energy (VHE), Galactic gamma-ray source recently discovered at >50GeV using the Large Area Telescope (LAT) on board the Fermi-LAT. Thi…
The Accretion History of AGN I: Supermassive Black Hole Population Synthesis Model
Tonima Tasnim Ananna, Ezequiel Treister, Claudia Megan Urry +6
As matter accretes onto the central supermassive black holes in active galactic nuclei (AGN), X-rays are emitted. We present a population synthesis model that accounts for the summ…
SMBH accretion properties of radio-selected AGN out to z~4
I. Delvecchio, V. Smolcic, G. Zamorani +8
Exploring how radio-emitting active galactic nuclei (AGN) behave and evolve with time is critical for understanding how AGN feedback impacts galaxy evolution. In this work, we inve…
Identifying the 3FHL catalog: I. Results of the KOSMOS optical spectroscopy campaign
Stefano Marchesi, Amanpreet Kaur, Marco Ajello
We present the results of the optical spectroscopy follow-up of a sample of 28 unclassified blazars from the Third Fermi-LAT Catalog of High-Energy Sources (3FHL). All the spectra…
Low-luminosity AGN and X-ray binary populations in COSMOS star-forming galaxies
Francesca M. Fornasini, Francesca Civano, Giuseppina Fabbiano +4
We present an X-ray stacking analysis of 75,000 star-forming galaxies between using the Chandra COSMOS Legacy survey to study the X-ray emission of low-luminosity…
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…
Intermediate-mass black holes in dwarf galaxies out to redshift 2.4 in the Chandra COSMOS Legacy Survey
M. Mezcua, F. Civano, S. Marchesi +3
We present a sample of 40 AGN in dwarf galaxies at redshifts 2.4. The galaxies are drawn from the \textit{Chandra} COSMOS-Legacy survey as having stellar masses $10^{7…
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…
The NuSTAR Extragalactic Surveys: source catalog and the Compton-thick fraction in the UDS field
A. Masini, F. Civano, A. Comastri +19
We present the results and the source catalog of the NuSTAR survey in the UKIDSS Ultra Deep Survey (UDS) field, bridging the gap in depth and area between NuSTAR's ECDFS and COSMOS…
