In the past decade many extragalactic 3CR sources have been observed by Spitzer,Hubble and Chandra as well as in the radio band at different frequencies. Inparticular, we successfully carried out the X-ray survey for all the unobserved3CR sources with z<1 with Chandra. However we discovered that 20 sources out of298 are still unidentified. Here we propose a snapshot program with XMM-Newtonfollow up observations that will allow to detect the X-ray emission arising fromthe core of these unidentified 3CR sources and to improve the localization ofthe optical counterparts. Thanks to the proposed XMM-Newton observations we willbe also able to obtain the first X-ray observations of obscured radio-loudsources in the 3CR catalog since none of those listed as obscured have been yet pointed in the X-rays.

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.
