    Quantitative Morphology of the Intermediate-Redshift Galaxy Cluster Abell 2443 from Ground-based Imaging: Evidence for a Galaxy Concentration Index Correlation with Cluster Density
    We present broadband photometry and provide a quantitative analysis of the structure of galaxies in the inner region of the Abell Cluster 2443 (z~0.1). The...
