|Title||X-RAY SPECTROSCOPY OF GAS-POOR GALAXIES WITH ERMASSIVE BLACK HOLES|
|Author||Dr MICHAEL LOEWENSTEIN|
|Description||We propose to observe five X-ray faint galaxies with secure dynamical evidence for the presence of supermassive black holes (SMBHs) and previously detected low-luminosity nuclear X-ray emission. Our primary goal is to obtain and analyze EPIC spectra of the nuclei in order to clarify the nature of the emission mechanism and compare them with more luminous systems, with each other, and with theoretical expectations. Our secondary goal is to study the thermal and chemical characteristics of hot gas in X-ray faint elliptical galaxies. Observations that are optimal for addressing these issues do not presently exist.|

|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.
