Free format text (please update) One of the most intriguing results from HST has been the discovery of ultraluminous star clusters in interacting and merging galaxies. These clusters have the luminosities, colors, and sizes that would be expected of young globular clusters produced by the interaction. We propose to use the data in the HST Archive to determine how prevalent this phenomena is, and to determine whether similar clusters are produced in other environments. Three samples will be extracted and studied in a systematic and consistent manner: 1) interacting and merging galaxies, 2) starburst galaxies, 3) a control sample of ``normal'' galaxies. A preliminary search of the archives shows that there are at least 20 galaxies in each of these samples, and the number will grow by about 50 \ observations become available. The data will be used to determine the luminosity function, color histogram , spatial distribution, and structural properties of the clusters using the same techniques employed in our study of NGC 7252 (``Atoms -for-Peace'' galaxy) and NGC 4038/4039 (``The Antennae''). Our ultimate goals are: 1) to understand how globular clusters form, and 2) to use the clusters as evolutionary tracers to unravel the histories of interacting galaxies. Questions !
