Query: Characteristics of Kiso Ultra-Violet Excess Galaxies   We examined the general characteristics of the Kiso Ultra-violet Excess
Galaxies (KUGs). We present for the first time the quantitative expressions for
the criteria of the KUGs; the boundary color separating the KUGs from the
non-KUGs is (B-V)_{T} = 0.74 and the KUG degrees of UV strength are found to
correlate with the mean (B-V)_{T} colors. We investigate the nature of the
KUGs, a sample of blue galaxy population, and show that (1) about a half of the
KUGs are spiral galaxies with Sb to Scd, (2) the KUGs are biased to late-type
galaxies and include early-type galaxies with young star populations, and (3)
the KUGs are preferably found among less luminous galaxies with log L(B) < 10.
The KUGs also contain the post-starburst galaxies, many of which are found
among the blue galaxy population at intermediate redshifts. The analysis of the
far-infrared data shows that a typical present-to-past star formation rate for
a KUG is 0.4.
