| Abstract | We propose to observe a known TeV blazar in outburst. The observation will besupported by coordinated ground-based observations at TeV energies. The mainthrust of the proposed observation is to study the flaring phenomenon onsub-hour timescales jointly at X-ray and TeV energies. XMM covers a criticalspectral range for studying TeV blazars, because the SED of such sources peaksin or near its passing band. The data will also allow investigations ofcorrelated variability of the X-ray and TeV emission, spectral hysteresis, andhardness-intensity correlation. The results may shed significant light on theproperties of emitting regions in the jet of TeV blazars, emission mechanisms,and the composition of the jet (i.e., leptonic vs hadronic). |

| 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. |
