The big picture of AGN feedback: Black hole accretion and galaxy evolution in multiwavelength surveys

TL;DR

This paper reviews how large multiwavelength surveys reveal the interconnected evolution of supermassive black holes and galaxies, highlighting recent findings on AGN feedback effects and future observational prospects.

Contribution

It synthesizes recent observational results linking black hole accretion states with galaxy properties and discusses how these insights constrain galaxy-SMBH co-evolution models.

Findings

Significant links between black hole accretion and galaxy stellar populations.

Correlations between AGN activity and local galaxy environments.

Potential of future X-ray surveys to advance understanding of AGN feedback.

Abstract

Large extragalactic surveys allow us to trace, in a statistical sense, how supermassive black holes, their host galaxies, and their dark matter halos evolve together over cosmic time, and so explore the consequences of AGN feedback on galaxy evolution. Recent studies have found significant links between the accretion states of black holes and galaxy stellar populations, local environments, and obscuration by gas and dust. This article describes some recent results and shows how such studies may provide new constraints on models of the co-evolution of galaxies and their central SMBHs. Finally, I discuss observational prospects for the proposed Wide-Field X-ray Telescope mission.
