Scientific paper

The nuclei of interacting galaxies were investigated as sites of recent star formation activity. A JHKL survey of 45 interacting galaxies reveals that, for 85% of the sample, 1 member of an interacting pair has a K-L color index significantly redder than normal galaxy colors. These K-L excesses imply steeply-rising infrared spectra characteristic of thermal emission by dust and similar to the infrared spectra found for the nuclei of canonical starburst galaxies. This inference is supported by 10 to 20 micron photometry obtained for a few of these galaxies. Thus, interactions trigger bursts of star formation in the nuclei of galaxies with efficiency approaching 100%.
