Description We propose to exploit the unprecedent troughtput of XMM-Newton to perform a systematic study of a sample of quasars in which previous less sensitive observations found evidences for X-ray absorption. The main goals are: 1- measure redshift and column density of the X-ray absorbers; 2- assess whether absorption at the quasar redshift occurs preferentially in radio-loud objects; 3- test the correlation between absortion and redshift suggested by ROSAT and ASCA data; 4- constrain the absorber ionization status and metallicity; 5- constrain the absorber dust content and composition through the comparison between the amount of X-ray absorption and optical dust extinction.

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.
