On the 28th of January, an orphan very-high-energy γ-ray flare from 3C279
was detected, not accompanied by flaring in the adjacent GeV gamma-ray
regime. Orphan flares have to be caused by different processes than normal
γ-ray flares. Specifically, the Hadronic Synchrotron Mirror Model has been
proposed to provide a consistent explanation of this flare. The expected tar-
get photon densities have been calculated analytically using the cloud/mirror
model. The results suggest that the Hadronic Synchrotron Mirror Model may provide a plausible explanation. A semi-analytical model has been developed to represent the Hadronic Synchrotron Mirror Model in a realistic fashion. Our analytical estimates are confirmed by detailed numerical simulations of the Hadronic Synchrotron Mirror scenario, predicting snap-shot SEDs and light curves as well as neutrino emission.
