INVESTIGATING THE ELEMENTAL ABUNDANCE PARADOX IN ELLIPTICAL GALAXIES WITH XMM

Essential clues to the structure and history of elliptical galaxies lie embeddedin their hot Xray emitting halos. XMMNewton observations, in conjunction withoptical data and detailed theoretical modeling, offer the unique opportunity toobtain sufficient counts on all r^ant lengthscales to study the relationshipbetween dark and luminous matter, and constrain the earliest star formation inellipticals. We therefore propose to observe two elliptical galaxies, NGC 4374and NGC 5813, with extended thermal Xray emission and excellent opticalspectroscopy. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
