We propose to perform a set of simultaneous X-ray--TeV observations with XMM andHESS, on the 3 best candidates for new TeV blazars in the southern emisphere. Weask for 10 ks in 7 consecutive nights, corresponding to the HESS visibilitytimes, for each source. This strategy optimizes the simultaneous X-ray--TeVcoverage while allowing to sample two different variability timescales: theshortest ones (subhour) and the typical flaring timescale of TeV blazars (one tofew days). Our final goal is to strongly constrain the emission models studyingwith unprecedented detail the evolution of the particle distribution on thesetwo scales, shedding light onto the acceleration mechanism and allowing todisentangle the absorption effects from the blazars intrinsic TeV spectra.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
