3C 279 is one of the best studied flat spectrum radio quasars located at a comparatively large redshift of z = 0.536. Observations in the very high energy band of such distant sources were impossible until recently due to the expected steep energy spectrum and the strong gamma-ray attenuation by the extragalactic background light photon field, which conspire to make the source visible only with...
Intensive monitoring of the innermost jet in the quasar 3C 279 at 43 GHz from 1998 March to 2001 April with the Very Long Baseline Array, in combination with previous observations, reveal (1) an increase in apparent speed from 5c to 17c and (2) a change in projected direction of the jet by 20 . These effects could result from a small increase in the intrinsic viewing angle of the jet nozzle fro...
The measured spectral energy distribution and variability time scale are used to determine the radiation and magneticfield energy densities in the relativistic plasma that forms the gamma-ray emitting jet in the blazar 3C 279. Assuming that protons are accelerated as efficiently as electrons to a maximum energy determined by the size and magnetic field of the emitting region, we calculate the e...
