Conference paper


The relationship between galaxy encounters and activity of galaxies, particularly in small groups, has been studied in model calculations. We have shown the important role of the interstellar gas which can dissipate the collisional energy. Gas exchange (loss or gain) is possible. The gain of gas is especially important, as it can initiate activity in galaxies.
