|Title||X-ray Spectroscopy of the Early-Type Elliptical Galaxy NGC4636|
|Author||Dr Albert Brinkman|
|Description||GT - NGC 4636 is one of the brightest early-type elliptical galaxies. Studying the extended X-ray emission from the interstellar medium (ISM) of early-type galaxies is an important way to understand the evolution of these galaxies. ASCA and ROSAT observations have yielded unexpected, yet sometimes controversial, sub-solar metal abundances for the ISM of these galaxies. We propose a 100 ksec observation of NGC 4636 using the RGS as the primary instrument. It will perform high-resolution spectroscopy and determine the temperature distribution and chemical abundances of the X-ray emitting plasma. The EPICs in full window mode with the medium filter will be used to perform spatially-resolved spectroscopy.|

|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.
