THE EVOLUTION OF ISOLATED ELLIPTICAL GALAXIES


ABSTRACT

We propose to observe five galaxies from a unique sample of 23 nearby, isolated ellipticals for which we have extensive optical and IR data. There is no X-ray spectroscopy available for these galaxies. Our project has two broad goals: (1) to determine the X-ray properties of isolated ellipticals and compare them with ellipticals in the richer environments of groups and clusters and (2) to search for a diffuse X-ray halo characteristic of an intragroup medium which would provide direct evidence that ellipticals can evolve from the merger of groups.
