On the Origin of Rapid Flares in TeV Blazars
The rapid variability of the VHE emission reported for some TeV blazars implies Doppler factors well in excess of those inferred from superluminal motions and unification schemes. We propose that those extreme flares may result from radiative deceleration of blobs on scales where local dissipation occurs. The minimum jet power estimated from the resolved synchrotron emission on VLBI scales appe...
متن کاملThe Synchrotron Peak Shift during High-Energy Flares of Blazars
A prediction for the energy shift of the synchrotron spectrum of flat-spectrum radio quasars (FSRQs) during high-energy flares is presented. If the γ-ray emission of FSRQs is produced by Comptonization of external radiation, then the peak of the synchrotron spectrum is predicted to move to lower energies in the flare state. This is opposite to the well-known broadband spectral behavior of high-...
متن کاملGamma-ray Flares and Vlbi Outbursts of Blazars
A model is developed for the time dependent electromagnetic radio to gamma-ray emission of active galactic nuclei, specifically, the blazars, based on the acceleration and creation of leptons at a propagating discontinuity or front of a self-collimated Poynting flux jet. The front corresponds to a discrete relativistic jet component as observed with very-long-baseline-interferometry (VLBI). Equ...
متن کاملX-ray spectral variability of TeV blazars during rapid flares
The spectral energy distribution (SED) of TeV blazars peaks both at keV and TeV energies. The X-ray emission is generally believed to originate in the synchrotron emission from relativistic electrons (and positrons) in the jet of these sources, while the origin of the gamma-ray emission is still being debated. We report results from a systematic study of X-ray spectral variability of Mrk 421 an...
متن کاملHadronic Production of Tev Gamma Ray Flares from Blazars
We propose that TeV γ-ray emission from blazars is produced by collisions near the line of sight of high energy jet protons with gas targets (“clouds”) from the broad emission-line region (BLR). Intense TeV γ-ray flares (GRFs) are produced when BLR clouds cross the line of sight close to the black hole. The model reproduces the observed properties of the recently reported very short and intense...
