Do AGN suppress star formation in early-type galaxies?
Kevin Schawinski
TL;DR
This paper explores whether active galactic nuclei (AGN) suppress star formation in early-type galaxies, focusing on their placement in the green valley and implications for galaxy evolution.
Contribution
It provides an analysis of the colors of AGN host galaxies, especially early-types, to understand AGN's role in star formation suppression.
Findings
AGN host galaxies often found in the green valley
Early-type AGN hosts show signs of suppressed star formation
Implications for galaxy and black hole co-evolution
Abstract
The observation that AGN host galaxies preferentially inhabit the "green valley" between the blue cloud and the red sequence has significant consequences for our understanding of the co-evolution of galaxies and black holes via accretion events. I discuss the interpretation of green valley AGN host galaxy colours with particular focus on early-type galaxies.
