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…
X-ray spectral and eclipsing model of the clumpy obscurer in active galactic nuclei
Johannes Buchner, Murray Brightman, Kirpal Nandra +2
We present a unification model for a clumpy obscurer in active galactic nuclei (AGN) and investigate the properties of the resulting X-ray spectrum. Our model is constructed to rep…
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…
