A spectroscopic survey of X-ray-selected AGNs in the northern XMM-XXL field

This paper presents a survey of X-ray-selected active galactic nuclei (AGNs) with optical spectroscopic follow-up in a ∼ 18 deg2 area of the equatorial XMM-XXL north field. A sample of 8445 point-like X-ray sources detected by XMM–Newton above a limiting flux of $F_{\rm 0.5{\rm -}10\, keV} > 10^{...
