Resumen
The TexOx Cluster (TOC) Survey has found more than 10 previously unknown galaxy clusters and cluster candidates in the first of four fields that it is surveying. These clusters form a unique sample of "radio-active" clusters: clusters rich in powerful radio sources. Preliminary photometry of a subset of fields with multi-color data shows that these clusters have a high fraction of blue galaxies, and the blue galaxies and radio sources both tend to be less centrally concentrated than the red cluster galaxies. These properties are typical of Butcher-Oemler effect clusters.
