Abstract We propose a 150 ksec ACIS-S/LETGS observation of the proto-type Big Blue Bumpquasar, PG 1211+143. In our recent XMM-Newton observation, we found evidence forone of the most extreme X-ray outflows yet observed in an AGN. Indeed theoutflow velocity (0.1c) and kinetic output are similar to that seen in the mostpowerful BAL quasars. We will utilize the high spectral resolution, bandpass andsensitivity of the ACIS-S/LETGS combination to measure the outflow velocities ofthe highly ionized absorption lines of N, O, Ne, Mg, Si, and S in the soft X-rayband, to fully understand the dynamics of this extraordinary outflow. We also request a simultaneous, 50 ksec XMM-Newton observation to detect the blueshifted Fe XXV and Fe XXVI K-shell lines, with the EPIC detectors above 6 keV.

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.
