Description We request to observe 7 Roma-BZCAT high redshift (z>3) blazars with XMM. These sources are some of the most powerful of their class but crucially lack of X-ray measurements. We propose to observe them in the X-ray with XMM, and in the optical with the supplementary observations from the optical monitor (OM). The XMM observations will allow us to accurately measure the rising part of the inverse Compton spectrum, which is expected to be very hard. The X-rays will be fundamental to determining the power of the jet and to deriving the shape of the underlying electron population responsible for the emission. The optical data will reveal the powerful accretion disk emission that will enable us to measure accretion disk luminosity and derive the black hole mass of these sources.

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.
