Description

The detection of Flat Spectrum Radio Quasars (FSRQs) in the Very High Energy (VHE, E>100 GeV) range is challenging, mainly because of their steep soft spectra in this energy band. Up to now only four FSRQs have been detected in VHE, three of them discovered by MAGIC. The gamma-ray observations observations at such high energies are crucial to understand their emission, especially to constrain the localization of the emitting region within the jet due to the absorption from their broad line region (BLR). Typically, FSRQs are detected during high flux states, enhancing the probability of detection with the current instruments' sensitivities. However, the last observation campaigns performed with the MAGIC telescopes show emission during moderate-quiescent states, thus challenging our understanding of the emission mechanisms in FSRQs. In this contribution, we give an overview and present the most recent results of the three FSRQs 3C279, PKS1222+21 and PKS1510-089 in a multiwavelength context with special focus on MAGIC and Fermi-LAT.
