Polarization Swings Reveal Magnetic Energy Dissipation in Blazars [PDF]
, 2015 The polarization signatures of the blazar emissions are known to be highly variable. In addition to small fluctuations of the polarization angle around a mean value, sometimes large (> 180^o) polarization angle swings are observed. We suggest that such p
