Abstract

Compact Steep-Spectrum (CSS) radio sources are defined by their powerful yet subgalactic radio structure. High resolution radio interferometers reveal subarcsecond double, triple, and core-jet radio morphologies resembling miniature FR II sources. There are three promising scenarios for how such powerful radio sources could be so intrinsically small: 1) they are young sources which have not had time to grow large, 2) they are confined sources with exceptionally dense gas in the host which either smothers an existing source or frustrates its initial growth, or 3) they are enhanced sources with an intrinsic power much lower than one might expect based on their radio luminosity. To investigate these scenarios, we are continuing a comprehensive optical study of a sample of Compact Steep Spectrum objects.
