|Title||METAL ABUNDANCES IN LOW-REDSHIFT DAMPED LYMAN-ALPHA GALAXIES|
|Author||Prof RICHARD GRIFFITHS|
|Description||We propose to detect or to constrain the low-redshift photo-electric absorption caused by metals in low-redshift damped lyman-alpha systems. The measurements will be used to derive accurate metal-to-hydrogen ratios in the range 0.1 to 1 times solar. This program will lead to important results on the chmical enrichment history of the gaseous components of damped Lyman-alpha 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.
