Abstract | XMM-Newton RGS observations represent the state-of-the-art for high resolutionspectroscopy of high central X-ray surface brightness elliptical galaxies forthe foreseeable future. Since most previous observations are underexposed, wepropose to re-observe a carefully selected sample of ellipticals. In concertwith XMM-Newton 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. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
