Description Unification scenarios explain various flavors of radio galaxies and quasars with
orientation-dependent obscuration effects. Type-2 FRII galaxies contain a quasar
seen through a dusty molecular torus aligned with the radio jet. However, there
exist a population of FRIIs, found with Spitzer, that does not fit into this
scheme. These FRIIs exhbit high-excitation nuclear optical emission lines, but
weak 15um luminosities. One possibility is very large obscuration;
alternatively, they may be a genuinely different population. XMM spectroscopy
and Chandra imaging will discriminate between the two scenarios.

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.
