Scientific paper

XMM-Newton RGS observations represent the state-of-the-art for high resolution spectroscopy of high central X-ray surface brightness elliptical galaxies for the foreseeable future. Since most previous observations are underexposed, we propose to re-observe a carefully selected sample of ellipticals. In concert with XMM-Newton EPIC and/or Suzaku XIS data, we will (1) investigate the degree of temperature homogeneity and utilize these constraints (2) to unambiguously constrain the elemental abundances of N, O, Ne, Mg, Si, S, and Fe, and will evaluate and quantify the effects of (3) turbulence and (4) resonant scattering.
