The Fate of Luminous Compact Blue Galaxies: An Environmental Approach
  Luminous Compact Blue Galaxies (LCBGs) are a heterogeneous class which dominate an intermediate phase of galaxy evolution. These sources account for the majority of the star formation between 0.3<z<1, yet the identity of their present-day counterparts is an open question. An environmental dependence to their evolution may provide the answer. We have undertaken the first census of LCBGs in intermediate-redshift clusters using broad and narrow-band images from the WIYN Long Term Variability Study. Several key clusters are in the southern sky. The Southern African Large Telescope's (SALT) Prime Focus Imaging Spectrograph (PFIS), with a field of view matching our WIYN data, will allow us to determine several fundamental characteristics of cluster LCBGs, including (1) star formation rates (SFR) and metallicities from low dispersion Mulit-Object Spectroscopy (MOS); (2) dynamical masses from line-widths measured via high dispersion MOS; and (3) cluster velocity dispersions of LCBGs relative to other cluster emission-line galaxies via Fabry-Perot imaging or MOS. We tentatively connect these distant galaxies with their local, evolved counterparts, and discuss how PFIS observations will enable us to make the physical distinction between LCBGs in clusters and the field.
