PI: Dr. Bernard J. McNamara New Mexico State University CoI: Dr. Jun Makino University of Tokyo, Graduate School of N Science CoI: Dr. Holger Baumgardt Universitat Bonn, Astronomische Institute, N Sternwarte CoI: Dr. Thomas Harrison New Mexico State University N CoI: Mr. Doug Hoffman New Mexico State University N ------------------------------------------------------------------------------------ Abstract We propose to search for an intermediate mass black hole (IMBH) in the core of the galactic globular cluster NGC 6266. Based on a comparison between the observed central surface brightness profiles of 38 globular clusters and state-of-the art N- body simultations, NGC 6266 offers the best hope of detecting an IMBH among these objects. This detection would be significnat for at least two reasons. It would be the first concrete discovery of an IMBH, revealing unique information about the environment in which these objects form, and second, its discovery would provide a powerful validation on the N-body simultations used to track the dynamical evolution of globular clusters. ------------------------------------------------------------------------------------ 11111( 4) -
