Title Triggered Observations of a LAT Monitored Blazar in Quiescence


DOI 10.5270/esa-jma612s
Author Prof Markus Boettcher
Description Most multiwavelength campaigns on blazars are triggered by a flaring state. Because of this strategy and the difficulty of measuring spectra and variability of blazars in low states, the quiescent states of blazars are poorly understood. XMM-Newton, in combination with Fermi-LAT, now offers the opportunity to do such studies. For this reason, we propose triggered observations of a blazar on the list of Fermi-LAT Monitored Blazars in quiescence, which we define as a Fermi-LAT detected flux above 100 MeV smaller than the lowest flux or upper limit ever measured by EGRET, for at least one week. 80 ksec of XMM-Newton exposure will be coordinated with intensive monitoring by the WEBT to obtain simultaneous radio through gamma-ray coverage.

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.
