|Title||Simultaneous XMM--HESS observations: testing the X-ray--TeV connection in BLLacs|
|Author||Dr Luigi Costamante|
|Description||We propose to perform a set of simultaneous X-ray--TeV observations on 2 TeV blazars in the southern hemisphere. We ask for 2 pointings of 20 and 15 ks each, on 2 consecutive XMM revolutions, matching the H.E.S.S. visibility window. This strategy maximizes the simultaneous coverage (4-5hrs),to sample the shortest variability timescales, and will allow to observe the source in 2 different states, as given by the characteristics flaring timescale of TeV blazars (one to few days). Our goal is to strongly test and constrain the emission models studying with unprecedented detail the changes in the particle distribution on these two scales, shedding light onto the acceleration mechanism and allowing to disentangle EBL absorption effects from the blazar intrinsic TeV spectra.|

|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.
