THE EVOLUTION OF ISOLATED ELLIPTICAL GALAXIES


ABSTRACT

We propose to observe two galaxies from a unique sample of nearby, isolated elliptical galaxies for which we have extensive optical and IR data. Both of our targets are among the brightest ellipticals detected in the ROSAT All-Sky Survey, but neither target has available X-ray spectroscopy. Our project has two broad goals: (1) to determine the X-ray properties of isolated ellipticals and compare them to ellipticals in the richer environments of groups and clusters and (2) to search for the presence of an intra-group medium which will provide direct evidence that ellipticals can evolve from the merger of groups.
