Scientific paper

The properties of galaxy clusters in the local universe have been fairly well determined in the past few decades, and wide field surveys in the near infrared are converging on a statistically significant sample of high redshift clusters. These catalogs may soon allow discrimination between the competing models of galaxy formation and evolution [1]. The Oxford-Dartmouth Thirty Degree Survey (ODT) will span four widely separated 3° × 3° fields, to B < 26 in UBVRi'Z with an extension in the near-infrared to K < 19. With more than half of the survey completed, this deep, wide-area, multi-color dataset has yielded a large sample of K-selected clusters to probe the formation and evolution history of galaxies in dense environments. An exploration of cluster color-magnitude slopes and intercepts [2], luminosity functions [3], and morphological distributions [4, 5] should constrain the relative dominance of star formation rates and merger events on cluster galaxy evolution. Here, we present our cluster-finding method and preliminary results.
