Description | We propose to observe three quasars with large CIV emission-line blueshifts to identify and characterize their intrinsic absorption. XMM-Newton spectroscopy will provide a crucial test of the hypothesis that large CIV blueshift quasars are viewed with an orientation angle close to the line-of-sight of a disk wind producing the UV emission lines. Of our three targets, two have already shown evidence for X-ray absorption from exploratory Chandra observations. The third target, PG 1259+593, offers the potential for the first detailed absorption study of this class of quasar. |

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. |
