On the H I column density – radio source size anticorrelation in compact radio sources
Existing studies of the atomic hydrogen gas content in distant galaxies, through the absorption of the 21-cm line, often infer that the total column density, NHI, is anticorrelated with the linear extent of the background radio source, dem. We investigate this interpretation, by dissecting the various parameters from which NH I is derived, and find that the relationship is driven primarily by t...
متن کاملOutflows and shocks in compact radio sources
We report some key results from the optical emission line study of a complete sample of compact radio sources. We find strong evidence for jet-driven outflows in the circum-nuclear emission line gas namely: 1) highly broadened and blueshifted emission line components (up to 2000 km s), 2) shock ionised gas (broader, shifted components), 3) consistency in the scales of the emission line gas and ...

متن کاملFast outflows in compact radio sources: evidence for AGN-induced feedback in the early stages of radio source evolution
We present intermediate-resolution, wide-wavelength coverage spectra for a complete sample of 14 compact radio sources taken with the aim of investigating the impact of the nuclear activity on the circumnuclear interstellar medium (ISM) in the early stages of radio source evolution. We observe spatially extended line emission (up to ∼20 kpc) in the majority of sources which is consistent with a...
متن کامل86GHz VLBI survey of compact radio sources
Wepresent results from 86GHzVLBI1 observations of 28 compact radio sources made in April 1993. All but two of the observed objects are active galactic nuclei. The remaining two objects are the galactic center Sgr A∗ and the X-ray binary starCygnusX-3.Of the observed sources, 26haveyielded fringe detections. We present correlated flux densities, estimate the maximumobserved brightness temperatur...
