Author(s) from Durham


We briefly review the synergy between X-ray and infrared observations for active galactic nuclei (AGNs) detected in cosmic X-ray surveys, primarily with XMM-Newton, Chandra, and NuSTAR. We focus on two complementary aspects of this X-ray–infrared synergy: (a) the identification of the most heavily obscured AGNs, and (b) the connection between star formation and AGN activity. We also briefly discuss future prospects for X-ray–infrared studies over the next decade.
