%0 Conference Paper %D 2012 %T An estimation method for the minimum Doppler factor and energy content of quasar 3C 279 %A Petropoulou, M. %A Mastichiadis, A. %X In the present work we propose an estimation method for the minimum Doppler factor and energy content of the γ-ray emitting region of quasar 3C 279, using a standard proton synchrotron blazar model and the principles of automatic photon quenching. This estimation method can be regarded as an extension of the one for estimating the equipartition magnetic field. In our case the leptonic synchrotron component is replaced by the proton synchrotron emission and the radio by the VHE γ-ray observations. %V 1505 %P 643 - 646 %8 2012/12/1 %@ 0094-243X %G eng %U https://ui.adsabs.harvard.edu/abs/2012AIPC.1505..643P %!
