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

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
