Abstract

Amongst our sample of radio-excess IRAS galaxies, we have identified compact steep spectrum radio sources that fall into the classes of CSS or GPS sources, but have not previously been identified as such. The sample includes objects that have radio powers as low as ~1022 WHz-1. We suggest that these are low-power analogues of CSS and GPS sources, with weaker radio jets. These may be precursors to FRI radio galaxies or may ‘fade’ into radio-quiet galaxies.
