Description X-ray observations of blazars that emit TeV gamma-rays, have been rich with results on the variability of source fluxes and spectra and their correlations. However, the number of TeV bright blazars is small. To increase this sample, the highest energy EGRET gamma-rays were examined. We have identified the only flat spectrum radio quasar (FSRQ) to have a measured spectrum extending beyond 10 GeV. PKS1406-076 has emission lines and the high ratio of inverse-Compton to the synchrotron power that is typical of FSRQs, yet uniquely amoung FSRQs has emission extending to very high energies. We propose XMM observations to measure the upper frequency end of the synchrotron spectrum, to understand where this object fits in with the general theoretical picture of blazars.

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.
