Author Dr Zhiyuan Li
Description We propose deep XMM-Newton observations for three dwarf elliptical galaxies, NGC147, NGC185, and NGC205, in the Local Group, in order to measure and quantify the dispersion of the collective X-ray emissivity from old stellar populations. Precise knowledge of this kind is crucial not only for understanding the r^ant stellar astrophysics but also for reliably disentangling and quantifying the thermal emission from diffuse hot gas in nearby galaxies.

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.
