A deep X-ray look to the most obscured quasar at z~3.6 and its environment
I. Villani, L. Zappacosta, E. Piconcelli +17
The most luminous and obscured quasars (QSOs) detected in infrared all-sky surveys could represent a key co-evolutionary phase from nuclear to circum-galactic (CG) scales in the fo…
Evidence for universal gas depletion in a sample of 41 luminous Type 1 quasars at z 2
S. J. Molyneux, M. Banerji, M. J. Temple +9
We present ALMA CO observations of the molecular gas in a sample of 41 luminous unobscured quasars at z 2 from the Sloan Digital Sky Survey. 32 targets comprise the main sam…
BASS XLI: the correlation between Mid-infrared emission lines and Active Galactic Nuclei emission
M. Bierschenk, C. Ricci, M. J. Temple +22
We analyze the Spitzer spectra of 140 active galactic nuclei (AGN) detected in the hard X-rays (14-195 keV) by the Burst Alert Telescope (BAT) on board Swift. This sample allows us…
Why are optical coronal lines faint in active galactic nuclei?
Jeffrey D. McKaig, Shobita Satyapal, Ari Laor +4
Forbidden collisionally excited optical atomic transitions from high ionization potential (IP54.8\,eV) ions, such as Ca, Ne, Fe$^{\mathrm{6+}}…
New Spectral Model for Constraining Torus Covering Factors from Broadband X-ray Spectra of Active Galactic Nuclei
M. Baloković, M. Brightman, F. A. Harrison +6
The basic unified model of active galactic nuclei (AGN) invokes an anisotropic obscuring structure, usually referred to as a torus, to explain AGN obscuration as an angle-dependent…
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…
A New Compton-thick AGN in our Cosmic Backyard: Unveiling the Buried Nucleus in NGC 1448 with NuSTAR
A. Annuar, D. M. Alexander, P. Gandhi +22
NGC 1448 is one of the nearest luminous galaxies ( 10) to ours ( 0.00390), and yet the active galactic nucleus (AGN) it hosts was only recent…
A growth-rate indicator for Compton-thick active galactic nuclei
M. Brightman, A. Masini, D. R. Ballantyne +10
Due to their heavily obscured central engines, the growth rate of Compton-thick (CT) active galactic nuclei (AGN) is difficult to measure. A statistically significant correlation b…
