The Nuker Team was organized in 1985 to use the Hubble Space Telescope, with its high-resolution imaging and spectroscopy, to investigate the central structure and dynamics of galaxies. The team uses the space telescope to examine supermassive black holes and determined the relationship between a galaxy`s central black hole`s mass and velocity dispersion. The team continues to conduct research and publish papers on the supermassive black holes of galaxies and clusters.
