102MHz radio source survey

Listed in IVOA Registry (Virtual Observatory)

An analysis of 125 radio sources from a 102MHz survey of scintillating sources is presented.

Description

These compact (<1") radio sources are identified with radio sources in the most sensitive catalogs currently available. Analysis of the integrated spectra for these objects indicates that the compact sources have steep spectra ({alpha}>0.5).

There is a tendency for weaker sources to be more compact. The inferred spectral indices for compact sources in the cores of extended objects are on average lower than the integrated values. The most likely candidates for optical counterparts to the compact radio sources from the scintillating source survey are steep-spectrum quasars.
