H.E.S.S. detection of very-high-energy gamma-ray emission from the quasar PKS 0736+017
H. E. S. S. Collaboration, :, H. Abdalla +225
Flat-spectrum radio-quasars (FSRQs) are rarely detected at very-high-energies (VHE; E>100 GeV) due to their low-frequency-peaked SEDs. At present, only 6 FSRQs are known to emit VH…
