H{alpha} scale length in Virgo and field spirals

DOI

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 H{alpha} and broad R-band surface photometry. While the R-band and H{alpha} scale lengths are, on average, comparable for the combined sample, we find significant differences between the field and cluster samples. While the H{alpha} scale lengths of the field galaxies are a factor of 1.14+/-0.07 longer, on average, than their R-band scale lengths, the H{alpha} scale lengths of Virgo Cluster members are, on average, 20% smaller than their R-band scale lengths.
