Radio Galaxy Spectra | C A Jackson & J V Wall
; | Date: |
22 Dec 2000 | Subject: | astro-ph | Abstract: | Radio spectra of radio galaxies are often ascribed a simple power law form ($S_{
u} propto
u^{alpha}$) with the spectral index, $alpha$, being of order -0.7. However, all radio galaxies deviate from this simple power law behaviour. In this paper we derive simple expressions for the average rest-frame spectra of FRI and FRII radio galaxies. These will be used to describe the spectral curvature of the parent (FRI and FRII) populations in models of radio source evolution. | Source: | arXiv, astro-ph/0101367 | Services: | Forum | Review | PDF | Favorites |
