|Title||An X-ray Study of the Most Distant Quasars from the Sloan Digital Sky Survey|
|Author||Prof William Brandt|
|Description||We propose to begin a systematic X-ray study of the highest redshift quasars found by the Sloan Digital Sky Survey (SDSS). Here we propose observations of the three highest redshift quasars found by the SDSS to date (z=4.9-5.0). SDSS quasars are selected in a uniform and highly effective manner, and they are ideal for defining the basic X-ray properties of the youngest known quasars. The observations will constrain the X-ray luminosity function of the highest redshift quasars and will identify any objects bright enough for X-ray spectroscopy. We intend to expand this investigation as additional SDSS quasars are found, with our ultimate goals being to determine the evolution of quasar X-ray power sources and environments.|

|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.
