Title21 Centimeter Study of Spiral Galaxies in the Coma Supercluster
AuthorsGavazzi, Giuseppe
Bibcode

1987ApJ...320...96G   Search ADS ↗

AbstractHigh-sensitivity, 21 cm line observations of 130 galaxies in the Coma/A1367 Supercluster region are presented and used to study the large-scale distribution of galaxies in the direction of the Coma Supercluster and the H I content in spiral galaxies as a function of the local galaxy density. Groups of galaxies are found to form a quasi-continuous structure that connects the Local Supercluster to the Coma Supercluster. This structure is composed of real filaments only in the vicinity of the Coma Cluster. Spiral galaxies in the surveyed groups and multiple systems have H I content not dissimilar from that of isolated galaxies. Galaxies within about 1 Abell radius from the Coma Cluster contain about three times less hydrogen on average than isolated galaxies. There is a strong tendency for galaxies that are more severely H I-depleted to be redder and of earlier Hubble type. In the Coma Cluster a considerable fraction of late-type, blue galaxies have large deficiency parameters.
