Scientific paper

In Paper I (38.157.003) the authors used JHKL photometry of a sample of interacting galaxies to argue that interactions induce a burst of star formation in the nucleus of one member of the interacting pair with nearly 100 per cent efficiency. The authors have followed up this result by mid-infrared (10 and 20 μm) observations of a large fraction of this sample. They have added to these results existing mid-infrared data in the literature to obtain a comprehensive picture of the evidence for mid-infrared activity in the nuclear regions of interacting galaxies. The authors show that this information, combined with radio and optical data, provides a consistent picture of interaction-induced bursts of star formation in the central regions of these galaxies. Using a simple analytical starburst model they derive some of the quantitative features of these interaction-induced starbursts.
