Abstract | We propose observations of three Low-Ionization Broad Absorption Line (LoBAL)Quasars with unusual properties. UN J1141-0143 is the most radio-loud LoBALquasar known, and only the second classical radio double BAL quasar known.SDSS 0300+0048 has LoBAL troughs spanning at least 13000 km/s with localcovering factor 50-100%, so that 90% of the rest-frame UV flux blueward of Mg IIis absorbed. Nonetheless, its BAL gas column density may be the same as in lessextreme LoBAL quasars; X-ray observations are needed to test this possibility.SDSS 2215-0045 is a unique bright LoBAL quasar with stronger absorption fromFe III than from Fe II. The reasons for its unique UV spectrum are unknown;X-ray observations will narrow the list of possibilities. |

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. |
