Abstract:

We present deep optical and near-infrared imaging as well as optical spectroscopy of as yet unclassified hosts of Gigahertz Peaked Spectrum (GPS) radio sources. Identifications were obtained for 14 objects, several of which are new. Spectroscopic follow-up yielded redshift information on 7 GPS objects. The remaining 18 objects of our sample without redshifts await spectroscopy with 8 m class facilities.

Key words: galaxies: active -- galaxies: distances and redshifts -- (galaxies:) quasars: emission lines
