For anyone intererested, I have myself suggested that the redshift of
galaxies is in fact caused by the small scale electric field due to
the intergalactic plasma (a kind of counter-part to the Faraday
-rotation in a magnetic field)

Perhaps of some interest would be to read some of the following works
by Ruth A. Daly et al: http://www.bk.psu.edu/faculty/daly/

Cheers,

I had a look at Ruth Daly's works but couldn't really find anything
that would directly apply here. As mentioned, of interest would be in
particular data of objects where the redshift factor has been measured
independently in the optical and radio region of the spectrum. I found
some data published in the book 'Radio Recombination Lines (Ed. P.A.
Shaver)', but the corresponding radio lines have a wavelength of the
order of 1 cm which is probably still about 2 orders of magnitude
smaller than the average distance between charged particles in the
intergalactic plasma, i.e. the redshift factor would not be affected
yet by the inhomogeneities of the small scale electric field.
If anybody knows redshift factors determined for even greater
wavelengths, I would appreciate any information in this respect.
