After studying VLA and Keck data on 26 galaxies and quasars, Wardle, Perley and Cohen conclude that «the observational data at both optical and
radio wavelengths show that any rotation of the plane of polarizaton over cosmological distances is unmeasurably small and is indistinguishable from zero.»

Rampadarath explains: «Comparing the VLA images at
radio wavelengths to Chandra's X-ray observations and the hydrogen - emission detected by Hubble,
shows that features are not only connected, but that the
radio outflows are in fact the progenitors of the structures seen by Chandra and Hubble.
The frozen chemicals Greenberg was postulating would
show up not in
radio, however, but at infrared
wavelengths.
It represents the longest «time exposure» of SS 433 at
radio wavelengths, and thus
shows the faintest details.
However, the original Green Bean population
show little to no emission at
radio wavelengths.
Shorter
wavelength radio waves are thought to be emitted close into the root of the jet, so the result
shows that the magnetic field is stronger and better aligned at the root of the jet.
While the burst's afterglow
showed a steady decline in brightness at both optical and X-ray
wavelengths, that was not the case at
radio wavelengths.
