Abstract
A model of the Galaxy has been constructed which represents satisfactorily the radio-frequency surveys which have been made in the range 18·3 Mc/s to 1200 Mc/s. The model consists of a system of localized sources which are highly concentrated in the centre of the Galaxy and a disc of ionized interstellar gas whose properties are consistent with visual observations. It is suggested that the sources are rare members of Baade's population II and that they may be identified with the intense sources which have been observed to lie close to the galactic plane. The model requires the existence of a large isotropic component of radiation whose origin is probably extra-galactic.Keywords
