| Description | We propose to observe the cool (<1 keV) IC 1459 galaxy group with XMM-Newton/RGS for 120 ks. We will obtain a high quality spectrum with strong O VII-VIII and Fe XVII-XVIII emission lines. O VII has never been observed in an individual cluster or group of galaxies until our recent work. These lines will allow us to constrain the gas cooling rate with high accuracy and to understand the deficit of cool gas in clusters and groups of galaxies and the role of the AGN feedback in suppressing the cooling flows. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
