[61.06] Morphological study of a GALEX-selected sample of galaxies in the COSMOS field

M.A. Zamojski, D. Schiminovich (Columbia University), COSMOS Team, GALEX Science Team

We present a morphological analysis of a UV-selected sample of galaxies ranging from redshift z ~0.2-1.2. Galaxies were selected from deep GALEX imaging of the COSMOS field. Our morphological sample consists of over 10,000 galaxies detected in the near-ultraviolet by GALEX with bright (I<24) COSMOS counterparts and photometric redshifts. We computed concentration (C), asymmetry (A) as well as Gini coefficient, M20 (the second moment of the 20% brightest pixels) and clumpiness (S) values for all objects in our sample. We further complement our morphological analysis with other morphological and structural parameters from the COSMOS catalog. We will be presenting results from our study, and their implications on the evolution of star-forming galaxies over our redshift range.
