Minor galaxy mergers are major drivers of star formation
Around half of the star formation in the local universe arises from minor mergers between galaxies, according to data from the Sloan Digital Sky Survey. Disruptions to the shapes of spiral galaxies, caused by interactions with their smallest neighbours, points to increased star formation. Evidence suggests that minor galactic mergers are therefore important drivers of galaxy evolution.
