We present an analysis of the distribution and strength of star formation in three nearby small galaxy systems, which are undergoing a weak interaction, a strong interaction, and a merging process, respectively. The galaxies in all systems present widespread star-formation enhancements, as well as, in some cases, nuclear activity. In particular, for the two closest systems, we study the number-count, size, and luminosity distribution of H II regions within the interacting galaxies, while for the more distant, merging system we analyze the general distribution of the Hα emission across the system and its velocity field.

Abstract
We present an analysis of the distribution and strength of star formation in three nearby small galaxy systems, which are undergoing a weak interaction, a strong interaction, and a merging process, respectively. The galaxies in all systems present widespread star-formation enhancements, as well as, in some cases, nuclear activity. In particular, for the two closest systems, we study the number-count, size, and luminosity distribution of H II regions within the interacting galaxies, while for the more distant, merging system we analyze the general distribution of the Hα emission across the system and its velocity field.File in questo prodotto:
