Scientific paper

We propose to observe at high resolution the central regions of eight early-type galaxies, for which X-ray and radio continuum data are available. Four of these have radio core power comparable with that of M87, and four are radio quiet. We seek to measure the UV emission of a nonthermal nuclear source, and/or to find evidence of a central stellar spike, which could indicate the presence of a central mass concentration. These measurements will enable us to investigate the origin of nuclear activity in ellipticals with particular reference on the mass of the central black hole as a crucial element.
