Abstract We found that the gravitational potential of X-ray bright elliptical galaxiesgenerally consists of two components; a small-scale galaxy component and alargely extended component beyond galaxy scale. On the other hand, X-ray faintelliptical galaxies seem to possess only the galaxy-component. If it is true,elliptical galaxies must be classified into two types by only X-rayobservations, and it becomes important for the study of the evolution ofelliptical galaxies. In order to confirm this, we propose to observe an X-rayfaint elliptical galaxy IC1459 with Newton.

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.
