|Title||Completing the 3CR X-ray survey: the last unidentified radio sources in the Thir|
|Author||Dr Francesco Massaro|
|Description||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. In particular, we successfully carried out the X-ray survey for all the unobserved 3CR sources with z<1 with Chandra. However we discovered that 20 sources out of 298 are still unidentified. Here we propose a snapshot program with XMM-Newton follow up observations that will allow to detect the X-ray emission arising from the core of these unidentified 3CR sources and to improve the localization of the optical counterparts. Thanks to the proposed XMM-Newton observations we will be also able to obtain the first X-ray observations of obscured radio-loud sources in the 3CR catalog since none of those listed as obscured have been yet pointed in the X-rays.|

|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.
