A Cocoon Transparency and the 3C 345 Low Frequency Variability
The structure of the quasar 3C 345 is studied at λ = 49cm. The core has a low-frequency cut off spectrum and α ~ 3. The brightest knot is in the nearest part of the jet. The cocoon wall absorbs low-frequency emission and changes the polarization orientation, RM = 3500 rad m −2, B ∥ ~ 100 μG at the core region.
