The Contribution of Late-type/Irregulars to the Faint Galaxy Counts from HST Medium Deep Survey Images
ASTROPHYSICAL JOURNAL, no. 1 (1995): 48-64
摘要
We present a complete morphologically classified sample of 144 faint held galaxies from the HST Medium Deep Survey with 20.0 less than or equal to m(I) < 22.0 mag. We compare the global properties of the ellipticals and early- and late-type spirals and find a nonnegligible fraction (13/144) of compact blue [(V-I)less than or equal to 1.0 ...更多
