1995ApJ...453L..77W INTRACLUSTER GLOBULAR CLUSTERS MICHAEL J. WEST, PATRICK COTE, CHRISTINE JONES, WILLIAM FORMAN, AND RONALD O. MARZKE Received 1995 July 8; accepted 1995 August 28 ABSTRACT Globular cluster populations of supergiant elliptical galaxies are known to vary widely, from extremely populous systems like that of UGC 9799, the centrally dominant galaxy in Abell 2052, to globular- cluster-poor galaxies such as NGC 5629 in Abell 2666. Here we propose that these variations point strongly to the existence of a population of globular clusters that are not bound to individual galaxies but, rather, move freely throughout the cores of clusters of galaxies. Such intracluster globular clusters may have originated as tidally stripped debris from galaxy interactions and mergers, or, alternatively, they may have formed in situ in some scenarios of globular cluster formation. Subject headings: galaxies: clusters: general - galaxies: elliptical and lenticular, cD - galaxies: star clusters - X-rays: galaxies
