Star-forming galaxies in the 2dFGRS
Abstract
We examine the environment of star-forming galaxies selected in the 2dFGRS. We find that bright star-forming galaxies display a significant deficit of faint neighbours relative to passive galaxies. If a deficit in fainter companions implies a smaller mass halo, data support a scenario predicting star-formation to be suppressed in all systems more massive than 1013 Msun,rather than in clusters only.
