Abstract (from CDS):
We observe significant evolution of the linear polarization of the approaching component, with large rotations in position angle and a general decrease in fractional polarization. This may be the result of increasing randomization of the magnetic field within the ejected component. We do not at any time detect significant linear polarization from the core, including periods when the flux density from this region is dominated by radio oscillations. The power input into the formation of the jet is very large, ≥1038 erg.s–1 at 11 kpc for a pair plasma. If the plasma contains a cold proton for each electron, then the mass outflow rate, ≥1018 g.s–1, is comparable to inflow rates previously derived from X-ray spectral fits.
