Starburst Galaxies in Clusters

Abstract
The nature of the starburst phenomenon in galaxies is investigated using a narrow band color system designed to study color evolution in distant clusters. Work on zero redshift, luminous far-IR galaxies, calibrated by starburst models, demonstrates the usefulness of this color system in isolating starburst from normal star-forming colors, and also demonstrates a strong correlation with far-IR colors despite reddening effects. The same color system applied to distant clusters finds that a majority of the faint blue cluster population are starburst dwarf galaxies, probably the progenitor of the current population of dwarf ellipticals in nearby clusters.
