5. Abstract

We request support for an archival study of red galaxies in the Chandra Deep Field
South. We have identified a large sample of galaxies with red optical-to-IR colors
(I-K > 4) in the GOODS ACS images of the CDFS. We will use these data, and similar
data from a larger area survey by Rix et al., in conjunction with 8-color photometry
and redshifts from the Las Camanas IR survey to examine the nature of the red galaxy
population. Our sample contains more than 100 extremely red galaxies in the GOODS
CDFS field and will include an additional approximately 300 I-K > 4 galaxies in the
Rix et al. area. We will use quantitative morphological classification tools to
examine the morphologies of both the ERO population and the overall population of K-
band selected and photo-z sorted galaxies. This program will probe the 1 < z < 2
range, a critical epoch in the growth of galaxies and structure.
