Luminous Compact Blue Galaxies (LCBGs) appear to form a link between local, low mass HII galaxies and high-z, high luminosity Lyman Break Galaxies. Accounting for the majority of the star formation at intermediate redshifts (0.3 < z < 0.9), they represent a dominant phase of galaxy evolution; yet the identity of their present-day counterparts is an open question. We have undertaken a major survey of intermediate redshift galaxy clusters in search of LCBGs in order to connect this population of small, but powerful star forming galaxies to their present-day descendants through the morphology-density relationship. In this paper, we present the identification of LCBGs in two galaxy clusters, MS0451-0305 (z=0.538) and CL1604+4304 (z=0.90), and compare the photometric characteristics of cluster LCBGs to field LCBGs and other galaxy types. The LCBGs are identified through their broad and narrow band colors measured from deep imaging with the Mini-Mosaic camera on the WIYN 3.5m telescope. We use photometric redshifts and rest-frame [OII] λ 3727 emission in the narrow band images to identify star-burst galaxies associated with each galaxy clusters. LCBGs are too small for any detailed structural analysis from ground-based data, therefore we derived photometric characteristics (size, surface brightness, concentration, ellipticity, and asymmetry) from Archive HST WFPC2 and ACS imaging of the clusters. This work was supported by HST Archive grant #9917, NSF / AST-0307417, and an award from the Wisconsin Space Grant Corporation.
