The connection between AGN, star formation, and galaxy morphology
Abstract
We present a study of connection between activity of nuclear accretion, star formation, and galaxy morphology. We focus on mid-IR power-law emission selected AGNs, which are complementary samples of X-ray selected AGNs. We fit optical to far-infrared photometry by the latest SED techniques to derive stellar masses, star formation rates, dust properties, and AGN contribution in the COSMOS field. We also explore galaxy morphologies through ACS and WFC3 images, which provide structural properties of galaxy stellar component at high redshift. We compare AGN host galaxies with other star-forming galaxies and discuss the effect of nuclear activity on galaxy structures and their evolution. We find a possible correlation between star formation and AGN luminosity in our mid-IR selected sample, which provides another point of view to the claim of little correlation between the two.
