Polarimetry of GPS and CSS Sources

2 HI Absorption in GPS / CSS Sources

Combining our own observations with data from the literature, we consider the incidence of H I absorption in Gigahertz Peaked Spectrum (GPS) and Compact Steep Spectrum (CSS) sources. Here we present our preliminary results, where we find that the smaller GPS sources (< 1 kpc) on average have larger H I column densities than the larger CSS sources (> 1 kpc). Both a spherical and an axi-symmetric...

Polarisation in CSS/GPS radio sources

The polarisation properties of the intrinsically small (< 20 kpc) radio sources are briefly discussed. At centimetric and decimetric wavelengths, substantial polarised emission is often detected in quasars and, at a lower level, in radio sources identified with galaxies with projected linear sizes in excess of a few kpc. The projected linear size at which some polarised emission is detected dec...

X-ray Emission from GPS and CSS Sources

Many X-ray observations of GigaHertz Peaked Spectrum and Compact Steep Spectrum sources have been made with Chandra X-ray Observatory and XMM-Newton Observatory over the last few years. The X-ray spectra contribute the important information to the total energy distribution of the compact radio sources. In addition the spatial resolution of Chandra allows for studies of the X-ray morphology of t...
