Active Galactic Nuclei (AGN) are intensely accreting supermassive black holesat the centers of massive galaxies. Though these objects occupy little spatialextent of the galaxy itself, they are thought to have far reaching affects,impacting the galaxy's star formation, and possibly it's lifespan until itbecomes 'red and dead'. Typical galaxies demonstrate that, over cosmic time,they tend to separate into a bimodal distribution of 'red and dead' or blue andstar forming. We examine whether active galaxies evolve over cosmic time in asimilar way, and whether this can reveal anything about the complexities of therelationship between an AGN and the host galaxy. We use the Stripe82X survey toidentify 3940 X-ray AGN spanning z=0-2.5, and we measure the rest-frame UVJcolors of each galaxy. We classify AGN as star-forming or quiescent based ontheir location in a UVJ color diagram. We find that there is not a clearbimodal distribution between AGN in star forming and quiescent galaxies.Furthermore, the most luminous X-ray sources tend to lie in the star formingregion, which may indicate a correlation between central engine activity andincreased rates of star formation.
