|Title||XMM-Newton follow-up observations of AGILE-triggered gamma-ray flaring blazars|
|Author||Dr Stefano Vercellone|
|Description||We propose XMM-Newton observations of flaring blazars triggered by the AGILE gamma-ray satellite. For the first time after GCRO it will be possible to observe blazars during high gamma-ray activity states from a few keV up to a few GeV. This chance will be crucial to study the simultaneous spectral and temporal behaviour of blazars and to study the synchrotron to Inverse Compton (IC) transition region. Quasi-simultaneous observations by XMM-Newton and AGILE of blazars in active states will be important to establish the peaks of the nuFnu spectra, to study the broad-band SED, and to constrain the emitting particle distributions and acceleration mechanisms. We request 3 x 15 ksec XMM-Newton ToO observations (2 days apart) to cover the first major flare detected by AGILE.|

|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.
