Exploring the Diversity of Type 1 Active Galactic Nuclei Identified in SDSS-IV/SPIDERS
Julien Wolf, Mara Salvato, Damien Coffey +8
We present a statistical analysis of the optical properties of an X-ray selected Type 1 AGN sample, using high signal to-noise ratio () spectra of the counterparts of the R…
On the Prevalence of Super-Massive Black Holes over Cosmic Time
Johannes Buchner, Ezequiel Treister, Franz E. Bauer +2
We investigate the abundance of Super-Massive Black Hole (SMBH) seeds in primordial galaxy halos. We explore the assumption that dark matter halos outgrowing a critical halo mass M…
Active Galactic Nuclei and their Large-scale Structure: an eROSITA mock catalogue
J. Comparat, A. Merloni, M. Salvato +15
In the context of the upcoming SRG/eROSITA survey, we present an N-body simulation-based mock catalogue for X-ray selected AGN samples. The model reproduces the observed hard X-ray…
Galaxy gas as obscurer: II. Separating the galaxy-scale and nuclear obscurers of Active Galactic Nuclei
Johannes Buchner, Franz E. Bauer
The "torus" obscurer of Active Galactic Nuclei (AGN) is poorly understood in terms of its density, substructure and physical mechanisms. Large X-ray surveys provide model boundary…
Galaxy gas as obscurer: I. GRBs x-ray galaxies and find a N_H ~ M* relation
Johannes Buchner, Steve Schulze, Franz E. Bauer
An important constraint for galaxy evolution models is how much gas resides in galaxies, in particular at the peak of star formation z=1-3. We attempt a novel approach by letting l…
The Sloan Digital Sky Survey Quasar Catalog: twelfth data release
Isabelle Pâris, Patrick Petitjean, Nicholas P. Ross +43
We present the Data Release 12 Quasar catalog (DR12Q) from the Baryon Oscillation Spectroscopic Survey (BOSS) of the SDSS-III. This catalog includes all SDSS-III/BOSS objects that…
