Description We ask for 4 TOO observations of 50 ks each to observe 4 blazars, conditional to stringent and well defined triggering criteria based on 1) hard or soft X-ray brightening; or 2) TeV brightening; or GeV brightening or 3) optical brightening. With the XMM-Newton observations of blazars in flaring state we will investigate their X-ray spectra evolution over a timescale from minutes to hours. This will provide r^ant information on the radiation mechanisms in extragalactic relativistic jets. XMM-Newton TOO prompted by Swift-BAT or INTEGRAL or GLAST or TeV telescope would provide for the first time X-ray observations of flaring blazars activated by very high energy triggers. We will coordinate these observations with a similar Integral program already active.

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.
