		| Abstract: | 
		We explore the environment of AGN at z ≈ 1 using a sample of 130 spectroscopically identified X-ray sources in the All-wavelength Extended Groth strip International Survey. We quantify the local density in the vicinity of an X-ray source by measuring the projected surface density of spectroscopically identified optical galaxies within a radius defined by the 3rd nearest neighbour. We find that X-ray selected AGN at z ≈ 1 avoid, on average, underdense regions and share the same environment with optical galaxies of the similar U − B and MB. |
