HIGH RESOLUTION SPECTROSCOPY OF ELLIPTICAL GALAXIES

XMMNewton RGS observations represent the stateoftheart for high resolutionspectroscopy of high central Xray surface brightness elliptical galaxies forthe foreseeable future. Since most previous observations are underexposed, wepropose to reobserve a carefully selected sample of ellipticals. In concertwith XMMNewton EPIC and/or Suzaku XIS data, we will (1) investigate the degreeof temperature homogeneity and utilize these constraints (2) to unambiguouslyconstrain the elemental abundances of N, O, Ne, Mg, Si, S, and Fe, and willevaluate and quantify the effects of (3) turbulence and (4) resonant scattering. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
