| Description | TON 0599 is the flat spectrum radio quasar most recently detected in very high energy gamma rays. Analysis of the data taken during a flaring state revealed several interesting spectral features: i) apparent smooth spectral transition from the Fermi-LAT to MAGIC energy range, ii) inverse Compton (IC) peak between Fermi-LAT and MAGIC energy ranges, and iii) a spectral cut-off at few tens of GeV. Here we propose a monitoring campaign in order to study these spectral features in details. It will allow us to investigate the location of the gamma-ray emission region with respect to the broad line region and more detailed investigation of emission models. We also propose observations with XMM-Newton in order to investigate the transition from synchrotron to IC bump. |

| 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. |
