Enhanced activity in close dual-AGN systems in the local Universe

Lorenzo Battistini, Alessandra De Rosa, Paola Severgnini +16

We present the study of an X-ray selected sample of active galactic nuclei (AGN) in pairs at projected spatial separations 1 </kpc < 100 at z < 0.1, using XMM-Newton and Chan…
