SPIDERS: Selection of spectroscopic targets using AGN candidates detected in all-sky X-ray surveys
T. Dwelly, M. Salvato, A. Merloni +19
SPIDERS (SPectroscopic IDentification of eROSITA Sources) is an SDSS-IV survey running in parallel to the eBOSS cosmology project. SPIDERS will obtain optical spectroscopy for larg…
X-ray spectral properties of the AGN sample in the northern XMM-XXL field
Zhu Liu, Andrea Merloni, Antonis Georgakakis +7
In this paper we describe and publicly release a catalogue consisting of 8445 point-like X-ray sources detected in the XMM-XXL north survey. For the 2512 AGN which have reliable sp…
The clustering amplitude of X-ray selected AGN at z=0.8: Evidence for a negative dependence on accretion luminosity
G. Mountrichas, A. Georgakakis, M. L. Menzel +5
The northern tile of the wide-area and shallow XMM-XXL X-ray survey field is used to estimate the average dark matter halo mass of relatively luminous X-ray selected AGN [$\rm log\…
A Spectroscopic Survey of X-ray Selected AGN in the Northern XMM-XXL Field
Marie-Luise Menzel, Andrea Merloni, Antonis Georgakakis +10
This paper presents a survey of X-ray selected active galactic nuclei (AGN) with optical spectroscopic follow-up in a area of the equatorial XMM-XXL north fi…
Obscuration-dependent evolution of Active Galactic Nuclei
Johannes Buchner, Antonis Georgakakis, Kirpal Nandra +9
We aim to constrain the evolution of AGN as a function of obscuration using an X-ray selected sample of AGN from a multi-tiered survey including the CDFS, AEGIS-XD, COSM…
Strength of the =1.842 MeV resonance in the Ca(p,)Sc reaction revisited
Konrad Schmidt, Shavkat Akhmadaliev, Michael Anders +9
The strength of the MeV resonance in the Ca(p,)Sc reaction is determined with two different methods: First, by an absolute strength measurement…
