Statistics of faint galactic radiosources at the 7.6 CM wavelength from RATAN-600 observations.
Abstract
Surveys of three sections of the galactic plane within longitudes from 200° to 230° have been fulfilled with RATAN-600 and a high-sensitive radiometer at 7.6 cm wavelength. 405 sources were discovered out of which about 160 radio sources belong to the Galaxy. The statistics of the galactic radio sources shows a definite maximum near 80 mJy. The surface density of the sources is 6×103 sr-1, their radioluminosity ⪉ 4 Jy kpc2, and the half-width of the distribution over the galactic latitudes ≡15°. A comparison with the statistics of field stars shows that the observed number of sources cannot be explained by a recent star formation burst in the solar neighbourhood but is connected with the existence of a high-latitude population of faint galactic sources.
