The enhancement of infrared emission in interacting galaxies
Selected infrared properties, based on IRAS observations, of twocategories of interacting galaxy pairs from the Arp-Madore Catalogue ofSouthern Peculiar Galaxies and Associations are examined. For pairs ofcomparably sized galaxies, a strong tendency exists for pairs with thehighest far-IR color temperatures to have the smallest separation. Thisfinding implies that galaxy interactions significantly enhance theintensity or the efficiency of star formation. No trend of far-IR colortemperature varying with pair separation is found for pairs consistingof a galaxy with a small companion. There are 10 times as many pairs inthe sample that contain one IRAS far-IR galaxy as there are pairs forwhich both galaxies were detected by IRAS, thus strengthening previousconclusions that the effect of a perturbation depends strongly on thedetailed geometry of the interaction.
