Far-infrared and radio emission features of the galactic nuclear region

Abstract

In this paper the results of the Galactic nuclear region study in far-infrared and radio-wave bands are presented. Image processing methods are used for SkyView and IRSA archive images. On the basis of image synthesis, image analysis, and isophots the structure of the Galactic nuclear gas-dust disk and its borders are determined. Brightness temperature distribu-tions for gas and dust components of the disk and their average values (Ть8"3-! К, TV^-IO К) are obtained. Neutral HI and ionized H II hydrogen maps show non-symmetrical hydrogen distribution. Dust and gas maps indicate the presence of spiral and toroidal disk structure.
