A study of the environmental influences on spiral galaxies in clusters

Abstract

Gravitational fields in clusters as well as the hydrodynamic effects of the intracluster medium on the gas in galaxies are responsible for the observed differences between cluster and field galaxies. The thesis consists of two parts. The first part deals with the problem of atomic hydrogen deficiency in spiral galaxies in clusters. The second part describes a numerical study of the effects of the mean tidal field of a cluster on the dynamics of a disk galaxy travelling through it
