We propose to observe the cool (<1 keV) NGC 1404 elliptical galaxy with XMM-Newton/RGS and EPIC for 120 ks. We will obtain extremely high quality EPIC mapsand RGS spectra with strong O VII-VIII and Fe XVII-XVIII emission lines. We willestimate the spatial distribution of resonant scattering in NGC 1404 with RGSand constrain the gas cooling rate with high accuracy, and measure the Machnumber in different regions, dominated by different processes, such as mergingand ram- pressure stripping, to determine the processes that are heating the gasand preventing cooling, and quenching the AGN.

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.
