| Description | We propose to observe a known TeV blazar in outburst. The observation will be supported by coordinated ground-based observations at TeV energies. The main thrust of the proposed observation is to study the flaring phenomenon on sub-hour timescales jointly at X-ray and TeV energies. XMM covers a critical spectral range for studying TeV blazars, because the SED of such sources peaks in or near its passing band. The data will also allow investigations of correlated variability of the X-ray and TeV emission, spectral hysteresis, and hardness-intensity correlation. The results may shed significant light on the properties 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 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. |
