Scientific paper

The authors have obtained 1.2-10 microns photometry on a sample of galaxies selected from the preliminary Infrared Astronomical Satellite (IRAS) circulars. The sizes of their emission regions have been determined at 10 microns by comparing the flux densities determined by IRAS with those measured from the ground using a 5.5 arcsec beam. It is found that many infrared-selected galaxies have characteristic sizes of order 0.5-2 kpc radius. Galaxies with high 25/60 micron flux density ratios tend to be smaller than those with a low ratio. Galaxies that are compact and that have large 25/60 micron flux ratios tend also to have high 3.8/1.2 micron ratios, lending support to the idea that the 25/60 micron color of a galaxy is a good indicator of the presence of an active nucleus.
