| Abstract: |
We present high dynamic range VLBA images of the BL Lac objects Mrk 501 (1652+398) and 0814+425. Both sources show a similar total intensity structure: several sharp bends separated by straight jet segments, eventually broadening rapidly and becoming diffuse. Furthermore, the polarization structure of Mrk 501 shows a highly sheared layer at the edges, which is highly polarized with a magnetic field parallel to the jet direction, and a "spine" with a magnetic field orthogonal to the jet flow. We interpret the sharp bends as oblique shocks as the jet is deflected by clouds in the ambient material. |
