Description We request 3 separate observations of 30ksec each to perform temporal analysis
and precision spectroscopy of an intriguing Einstein ring source, PKS 1830-211.
Previous X-ray observations of the source have produced conflicting results, and
XMM-Newton observations are required to understand this system properly. With
the proposed observations we will measure accurately the spectral shape,
absorber column density and redshift and variability, if any. This will allow us
to determine the properties of the unusual source quasar, the face-on, spiral
lensing galaxy which appears to be a damped Lyman alpha absorber, and test the
suggestion of microlensing in the host galaxy of the source.

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.
