| Description | We have recently discovered a new class of flat-spectrum radio quasars (FSRQ) with synchrotron peak frequencies, nu_peak}, in the UV-X-ray band, set apart from ..classical. FSRQ, which typically have nu_peak in the optical-IR band. We propose to observe the eight FSRQ in the Deep X-ray Radio Blazar Survey with estimated nu_peak greater than 10**15 Hz to study their X-ray properties and pin down the emission process. The confirmation (or not) of the nature of FSRQ with high-energy synchrotron peaks and the subsequent detailed study of their properties have important implications for our understanding of jet formation and synchrotron cooling and their relationship to accretion disk properties and accretion rates in all radio-loud AGN. |

| 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. |
