POLARIZATION SWINGS REVEAL MAGNETIC ENERGY DISSIPATION IN BLAZARS

Dissipation of jet bulk kinetic energy in powerful blazars

Aims. We investigate the dissipation of the bulk kinetic energy of a relativistic jet at different distances from the central power–house and analyse in detail how the dissipated energy is radiated away. Methods. We assume that the location of the dissipation region is a function of the bulk Lorentz factor Γ of the jet, being closer to the center for smaller Γ. This assumption is naturally fulf...

Multifrequency Polarization Properties of Blazars

We report preliminary results of a 3-year multifrequency polarization campaign of 15 AGNs of blazar type, including bimonthly total and polarized intensity imaging at 7 mm with the VLBA. We find that the sources have two different dependences of degree of polarization on wavelength: sub-mm peaked or straight “polarization spectra”. The fractional polarization of the latter group increases with ...

A Method for Localizing Energy Dissipation in Blazars Using Fermi Variability

The distance of the Fermi-detected blazar γ-ray emission site from the supermassive black hole is a matter of active debate. Here we present a method for testing if the GeV emission of powerful blazars is produced within the sub-pc scale broad line region (BLR) or farther out in the pc-scale molecular torus (MT) environment. If the GeV emission takes place within the BLR, the inverse Compton (I...
