Scientific paper

We propose to combine HST archival data in the deep field of the Groth Survey Strip {dGSS} and in the clusters Cl0024, Cl0939, and Abell370 with deep near-infrared Keck observations, to identify and study a class of very faint {I gt 25} galaxies that have quite peculiar optical-infrared colors {V-I=0-2; I-K>4}. The colors of the ``red outlier galaxies,'' or ROGs, are not easy to reproduce, and are due to either an old underlying population of stars in the galaxy, or to a highly reddened bright nucleus central region. In either case, they are likely to lie at z gt 1.2. Combining the extant F606W and F814W HST data with the corresponding Keck K band {2.2Mu m} data, we will identify a large number of the ROGs since their surface density is rather high, several per square arcminute. Studying the numbers and morphology of ROGs found in the field and in or behind the {z 0.4} clusters will help distinguish between age and dust being responsible for the ROGs colors. This project will thus help us gain a better understanding of the formation epoch and history of galaxy evolution.
