The answer is yes. There is some polarization at IR and optical caused by
alignment of interstellar grains. AND for over 30 years its been well
established that quasars and radio galaxies are polarized--both linear and to
a lesser extent circular, at microwave.
Paul, I am not chiding you, but perhaps this escaped your memory.
