|Title||Testing the jet-accretion connection with radio powerful Low Excitation Galaxies|

|Description||We propose to observe 6 FRII LEG,never pointed by XMM. The observation of these sources will allow us to complete the X-ray nuclear survey of all the LEGs belonging to the 3CR sample with redshift z<0.3. The required time is 45 ks for each LEG. LEGs classified as FRII, share the same radio properties of FRII HEG, host similar massive black holes but are less bright in the [OIII] line by a factor of 10. Our goal is to verify whether the LEGs are a FRII class apart characterized by an inefficient accretion or radio galaxies with high Edd ratio (i.e. HEGs), seen through a thicker screen. Discriminating between these interpretations is fundamental.|

|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.
