The Swift BAT (14-195 keV) X-ray survey has currently identified a sample of 250nearby (z=0.03) AGN. Among these, two sources have very unusual multi wavelengthproperties which have strong implications for understanding similar sourcesdetected in deep surveys. In the optical, NVSS 193013+341047 and IRAS 05218-1212show broad lines, while their XRT spectra suggest these sources are heavilyabsorbed and possibly Compton-thick. Further, the IR properties of these sourcesplace them among the most heavily extincted with unusual SED, comparable only tohigh redshift ERO. With 15 ks XMM EPIC observations of both unusual sources, wewill constrain the X-ray properties of these sources, trying to determine theorigin of this unusual (at high flux) behavior.

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.
