|Title||Metal Abundances and Binding Mass in X-ray Faint Elliptical Galaxies|
|Author||Dr Dong-Woo Kim|
|Description||We propose a deep XMM-Newton observation (100 ks) of an X-ray faint elliptical galaxy, NGC 1316, to unambiguously determine Fe and alpha-element abundances. Our data (in conjunction with the existing Chandra data) will allow us to best map the diffuse gas at large radii and to accurately measure the gravitational binding mass. We will then address the origin of the large L_X-L_B scatter of early type galaxies in terms of ISM removal mechanisms and the amount of dark matter.|

|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.
