|Title||Rapid Flares from TeV Gamma-Ray Blazars|
|Author||Dr Wei Cui|
|Description||We propose to observe a known TeV gamma-ray 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 gamma-ray 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 gamma-ray emission, spectral hysteresis, and hardness-intensity correlation. The results may shed significant light on the properties of emitting regions in the jets of TeV gamma-ray blazars, emission mechanisms, and the composition of the jets (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.
