Abstract We propose observations of three extreme newly discovered radio-loud BroadAbsorption Line QSOs (BALQSOs). Previous ROSAT observations of radio-quietBALQSOs, which were the only kind known until recently, show that they are X-rayquiet compared to normal radio-quiet QSOs. This surprising result means thatBALQSOs are either (1) intrinsically X-ray-quiet, or (2) absorbed by high columndensity material (N_H = 1E23 cm-2 or higher). ASCA observations suggest thelatter. Radio-loud QSOs are more X-ray bright than radio-quiet QSOs. XMM can beused to obtain decent spectra of our radio-loud BALQSOs in modest exposure times(10 ks each) and verify that they are normal but absorbed radio-loud QSOs, andmeasure their power law spectral indices and columns.

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.
