The scale lengths of the old stars and ionized gas distributions are compared for similar samples of Virgo Cluster members and field spiral galaxies via Hα and broad R–band surface photometry. While the R–band and Hα scale lengths are, on average, comparable for the combined sample, we find significant differences between the field and cluster samples… CONTINUE READING
