Monitoring observations of the flat spectrum radio quasar TON 0599

TON 0599 is the flat spectrum radio quasar most recently detected in very highenergy gamma rays. Analysis of the data taken during a flaring state revealedseveral interesting spectral features: i) apparent smooth spectral transitionfrom the FermiLAT to MAGIC energy range, ii) inverse Compton (IC) peak betweenFermiLAT and MAGIC energy ranges, and iii) a spectral cutoff at few tens ofGeV. Here we propose a monitoring campaign in order to study these spectralfeatures in details. It will allow us to investigate the location of thegammaray emission region with respect to the broad line region and moredetailed investigation of emission models. We also propose observations withXMMNewton in order to investigate the transition from synchrotron to IC bump. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
