Accretion History of AGN II: Constraints on AGN Spectral Parameters using the Cosmic X-ray Background
Tonima Tasnim Ananna, Ezequiel Treister, Claudia M. Urry +5
We constrain X-ray spectral shapes for the ensemble of AGN based on the shape of the Cosmic X-ray Background (CXB). Specifically, we rule out regions of X-ray spectral parameter sp…
Unveiling Sizes of Compact AGN Hosts with ALMA
Yu-Yen Chang, Emeric Le Floc'h, Stéphanie Juneau +7
We present rest-frame far-infrared (FIR) and optical size measurements of AGN hosts and star-forming galaxies in the COSMOS field, enabled by high-resolution ALMA/1 mm (0.1 arcsec…
The Chandra COSMOS Legacy Survey: clustering dependence of Type 2 AGN on host galaxy properties
V. Allevato, A. Viitanen, A. Finoguenov +10
Aims. We perform clustering measurements of 800 X-ray selected Chandra COSMOS Legacy (CCL) Type 2 AGN with known spectroscopic redshift to probe the halo mass dependence on AGN hos…
The Accretion History of AGN: A Newly Defined Population of Cold Quasars
Allison Kirkpatrick, C. Megan Urry, Jason Brewster +15
Quasars are the most luminous of active galactic nuclei (AGN), and are perhaps responsible for quenching star formation in their hosts. The Stripe 82X catalog covers 31.3 deg o…
Compton-thick AGNs in the NuSTAR era. V: Joint NuSTAR and XMM-Newton spectral analysis of three "soft-Gamma" candidate CT-AGNs in the Swift-BAT 100-month catalog
Stefano Marchesi, Marco Ajello, Xiurui Zhao +3
We present the joint NuSTAR and XMM-Newton spectral analysis in the 0.6-70 keV band of three candidate Compton thick (CT-) AGN selected in the 100-month Swift-BAT catalog. These ob…
The composite nature of Dust-Obscured Galaxies (DOGs) at z~2-3 in the COSMOS field: II. The AGN fraction
Laurie A. Riguccini, Ezequiel Treister, Karín Menéndez-Delmestre +18
We present the X-ray properties of 108 Dust-Obscured Galaxies (DOGs; F/F 1000) in the COSMOS field, all of which detected in at least three far-infrared bands wit…
Cosmic evolution of supermassive black holes: A view into the next two decades
Francesca Civano, Nico Cappelluti, Ryan Hickox +38
The discoveries made over the past 20 years by Chandra and XMM-Newton surveys in conjunction with multiwavelength imaging and spectroscopic data available in the same fields have s…
Multi-wavelength properties of Type 1 and Type 2 AGN Host Galaxies in the Chandra-COSMOS Legacy Survey
Hyewon Suh, Francesca Civano, Guenther Hasinger +6
We investigate the multi-wavelength properties of host galaxies of 3701 X-ray-selected active galactic nuclei (AGNs) out to z~5 in the Chandra-COSMOS Legacy Survey. Thanks to the e…
Identifying the 3FHL catalog: CTIO results
Abhishek Desai, Stefano Marchesi, Meenakshi Rajagopal +1
Active galactic Nuclei (AGNs) with their relativistic jets pointed towards the observer, form a subclass of luminous gamma-ray sources commonly known as blazars. The study of blaza…
A closer look at the deep radio sky: Multi-component radio sources at 3-GHz VLA-COSMOS
E. Vardoulaki, E. F. Jiménez Andrade, A. Karim +20
In this data paper we present and characterise the multi-component radio sources identified in the VLA-COSMOS Large Project at 3 GHz (0.75 arcsec resolution, 2.3 μJy/beam rms), i.e…
Identifying the 3FHL catalog: I. Archival Swift Observations and Source Classification
Amanpreet Kaur, Marco Ajello, Stefano Marchesi +1
We present the results of an identification campaign of unassociated sources from the Fermi Large Area Telescope 3FHL catalog. Out of 200 unidentified sources, we selected 110 sour…
