| Abstract: |
Luminous compact blue galaxies (LCBGs) are common at z ∼ 1, contributing significantly to the total star formation rate density. By z∼0, they are a factor of ten rarer. While we know that LCBGs evolve rapidly, we do not know what drives their evolution nor into what types of galaxies they evolve. We present the results of a single-dish H I survey of local LCBGs undertaken to address these questions. Our results indicate that LCBGs have MHI and Mdyn consistent with low-mass spirals, but typically exhaust their gas reservoirs in less than 2 Gyr. Overall, the properties of LCBGs are consistent with them evolving into high-mass dwarf elliptical or dwarf irregular galaxies or low-mass, late-type spiral galaxies. |
