Abstract

We use data from the All Wavelength Extended Groth Strip International Survey to construct stacked X-ray maps of optically bright active galactic nuclei (AGNs) and an associated control sample of galaxies at high redshift (z ∼ 0.6). From our analysis of the surface brightness profiles obtained from these X-ray maps, we find evidence of feedback from the active nuclei. We find that excluding galaxies and AGNs, residing in group environments, from our samples enhances the significance of our detection. Our results support the tentative findings of Chatterjee et al., who use X-ray-selected AGNs for their analysis. We discuss the implications of these results in the context of quantifying AGN feedback and show that the current method can be used to extract an X-ray source population in high-redshift galaxies.
