Scientific paper
We propose to observe ten galaxies from a unique sample of nearby, isolated ellipticals for which we have extensive optical and near-IR data. We have three broad goals: (1) to determine the relationship, if any, between the X-ray halo mass and optical galaxy mass, (2) to compare the general properties of isolated ellipticals with those of ellipticals in denser environments, and (3) to search for direct evidence that ellipticals can evolve from the merger of poor groups. The sensitivity and spatial resolution of XMM makes it possible to examine the relationship between the X-ray and optical properties with a sample that is drawn from the same, simple environment and that is large enough to permit statistically significant results.
