|Title||The gravitational potential of X-ray Faint Eliptical Galaxy IC1459|
|Author||Dr Yasushi Fukazawa|
|Description||We found that the gravitational potential of X-ray bright elliptical galaxies generally consists of two components; a small-scale galaxy component and a largely extended component beyond galaxy scale. On the other hand, X-ray faint elliptical galaxies seem to possess only the galaxy-component. If it is true, elliptical galaxies must be classified into two types by only X-ray observations, and it becomes important for the study of the evolution of elliptical galaxies. In order to confirm this, we propose to observe an X-ray faint elliptical galaxy IC1459 with Newton.|

|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.
