Non-zero vorticity, necessary for that, might be created by the photon diffusion in the second order in the temperature fluctuations. The resulting seed fields at galactic scale would be only 4 orders of magnitude smaller than the observed ones and with a mild galactic dynamo amplifying the seed fields by the factor $\\sim 10^4$ an existence of coherent magnetic fields in galaxies may be explained.","authors_text":"A.D.
