The evolution of GHz-peaked-spectrum radio sources.

CARVALHO J.C.

Abstract (from CDS):

Observations of extended radio emission in some GPS sources suggest that they may not be a young version of the classical doubles. The compact source would be confined by the presence of a dense medium in the center of the galaxy. The existence of such a dense environment is supported by the observation of disturbed optical morphologies indicating galaxy-galaxy interaction or mergers. A simple model is formulated to calculate the velocity of advance of the jet as it propagates in a cloudy medium. Different forms of interaction of the jet with the clouds are studied as well as the distribution of gas and clouds on scales smaller than 1kpc around the central engine. It is found that the age of these GPS sources is of the same order as that of the extended radio sources and that the jet propagates either by scattering clouds or by drilling its way through them.

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!). sed-help-icon
