The large-scale radio spectral index distribution of Centaurus A
Abstract
A spectral index map of Centaurus A (Cen A) has been computed using 408 MHz observations from the whole-sky survey by \cite[Haslam et al. (1981)]{ref10} and new 1435 MHz 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.
