Scientific paper

The compact 'head' regions in the components of Cygnus A have been mapped with the 5-km telescope at 15.4 GHz, the resolution being 0.65 arcsec in right ascension and 1 arcsec in declination. The maps reveal, as had been inferred from preliminary 15-GHz observations with the 5-km telescope, that the 'head' in the Sf component has a sharply truncated leading edge. A comparison of the present data with those previously obtained at 5 GHz shows that the 'head' regions have spectral indices significantly lower than those of the lower-brightness 'tails'. Improved estimates have been obtained for the physical conditions within the various regions of the source.
