It is known since 1968 that the interaction of a pulse of light with matter redshifts the spectrum; the theory is clarified, to obtain the conditions for which, with incoherent light, one gets a redshift similar to a Doppler shift rather than Raman lines. The explanation of the appearance of the same absorption line with various z becomes trivial, requiring. only a static halo and a static magnetic field.
