Description A 2001 XMM spectrum of radio-loud AGN 3C 223 revealed that the line-of-sight column density is significantly different from the average global column density. Two qualities make 3C 223 remarkable: the implied obscuration geometry is a Compton-thick (>1.7 x 10^24 cm^-2) ring of gas embedded in a global Compon-thin (1.4 x 10^23 cm^-2) medium, and it is one of the very few radio loud Compton-thick AGN candidates known.

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.
