[11.13] Morphologies of AGN and their host galaxies at moderate redshifts

V. L. Sarajedini, C. Kasm (U. of Florida)

We explore the observed morphologies and light profiles of Active Galactic Nuclei (AGN) and their host galaxies at moderate redshifts (z\leq1.5). Several local Seyfert 1 and 2 galaxies from the Malkan et al. (1998) snapshot imaging survey with HST are modeled and decomposed into at least three components, including a central point source, bulge, and disk, using the two dimensional fitting algorithm GALFIT (Peng et al. 2002). We then artificially redshift each galaxy image, stepping out to z=1.5, using COSMOPACK (Balcells and Crostobal, in prep). We investigate how the galaxy light profiles change with redshift and also compare their redshifted morphologies to recently detected Seyfert galaxies in the Hubble Deep Field and Groth-Westphal Survey Strip. Support for this work is being provided by NASA through grant number GO-8389.02-A from STScI, which is operated by AURA under NASA constract NAS 5-26555.
