1997A&AS..121...11C The large-scale radio spectral index distribution of Centaurus A. Combi J.A., Romero G.E. Instituto, Argentino de Radioastronomia, C. C. 5, (1894) Villa Elisa, Prov. de Bs. As., Argentina Abstract. A spectral index map of Centaurus A (Cen A) has been computed using 408MHz observations from the whole-sky survey by Haslam et al. (1981A&A...100..209H) and new 1435MHz observations. The large-scale structure of the radio source is discussed in the light of these new data and a previous polarization survey. The observational evidence seems to support the expanding jet model for this source. Key words: galaxies: individual: NGC 5128 = Cen A - galaxies: active - radio continuum: galaxies
