Abstract

We present ultraviolet (UV) properties of dwarf galaxies in the Fornax and Ursa Major clusters in comparison with the Virgo cluster. Most of the dwarf galaxies in the Fornax cluster show red UV colors which is consistent with that the Fornax is dynamically evolved cluster with large fraction of early-type galaxies. Meanwhile, majority of dwarf galaxies of Ursa Major cluster are late-type with blue UV colors, indicating prevalence of strong star formation activities in the low density environment.
