Scientific paper
This archival proposal is to analyze WFPC2 and NICMOS images of distant clusters, which have complimentary ground-based narrow band photometry, to investigate the Butcher-Oemler effect. Our narrow band work has isolated a population of faint starburst galaxies in Butcher-Oemler clusters which may provide insight into the debate between the galaxy harassment models and gas supply proposals for the star formation behavior behind the Butcher-Oemler effect. The primary goal of this project is to determine the basic morphological and structural properties {scale lengths, surface brightness, bulge-to-disk luminosities} of the blue population in clusters and, in particular, to determine what kind of galaxy is involved in ordinary star formation versus a starburst phenomenon as assigned by narrow band colors. A newly discovered low luminosity starburst population will be studied to test whether they are future dwarf galaxies.
