MORPHOLOGY AND LIFE OF GALAXIES IN CLUSTERS

We present the first results on our study of the Coma cluster, as a pa rt of a larger project centered on the study of the properties of gala xies in different environments. Besides known results, we found that b lue spiral galaxies avoid the cluster center more than the whole spira l class. The galaxy group associated to the Rosat secondary clump 50' SW of the cluster center has a morphological composition richer in ear ly-type galaxies than is expected from a random density enhancement su ggesting a possible general tool to discriminate fortuitous alignments fi om real subclustering. Tile spatial distribution of disky elliptic als is not centered on the cluster center.
