Three Principal Heating Sources of Dust in the Galactic Disk
Conference paper
Abstract
The galactic infrared emission has been observed at various wavelengths from the near infrared 4 μm up to 900 μm. The spectrum of the central part of our galaxy is comparable to that observed towards external Sb/Sc galaxies: a broad emission peak centered around 100 μm and a distinct shoulder occuring shortwards of 20 μm. The presence of these features suggests that the infrared spectrum of normal spiral galaxies is a super position of spectra originating in different classes of sources (Fig. 1).
