Abstract | We propose to make XMM observations of two lensed BAL quasars that we expectwill yield high signal-to-noise detections. With these observations wewill constrain the BAL column densities, ionization state, search forcorrelations of BAL column densities with X-ray luminosity, opticalpolarization, and gas outflow velocities. Finally we will make use ofthe unique capability of XMM to simultaneously observe variableBAL systems in both the X-ray and UV bands and apply these findings to testthe validity of current BAL wind models. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
