## TL;DR

This study uses stacked X-ray maps of optically bright AGN and control galaxies at high redshift to detect feedback effects from active nuclei, supporting previous findings and demonstrating a method to analyze X-ray source populations.

## Contribution

It introduces a new approach to analyze stacked X-ray surface brightness profiles of optically selected AGN and compares them with X-ray AGN, highlighting feedback effects.

## Key findings

- Evidence of feedback from active nuclei in X-ray profiles
- Excluding group environment galaxies enhances detection significance
- Supports previous findings using X-ray selected AGN

## Abstract

We use data from the All Wavelength Extended Groth Strip International Survey to construct stacked X-ray maps of optically bright active galaxies (AGN) and an associated control sample of galaxies at high redshift (z less than 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 AGN, 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 AGN 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 X-ray source population in high redshift galaxies.
