| Description | The majority of broad absorption line quasars are X-ray weak which is usually explained by the absorption of the out-flowing wind in combination with the winds velocity shear. PG 0043-036 is the most extreme X-ray weak quasar known to date, but shows surprisingly only a very weak broad absorption line system. A conclusive interpretation is hampered by the absence of simultaneous measurements which is mandatory as both, the X-ray flux and the broad absorption system are known to be variable. We propose simultaneous XMM-Newton, HST (1 orbit) and 10m Hobby-Eberly or SALT Telescope observations in order to characterize simultaneously PG 0043-036.s X-ray emission and (broad) absorption (line system) properties. |

| 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. |
