The role of interactions in the evolution of highly star-forming early-type (Sa-Sab) spiral galaxies.

HAMEED S. and YOUNG L.M.

Abstract (from CDS):

We present a search for the signatures of galaxy-galaxy interactions in the neutral gas of early-type spirals. New neutral hydrogen observations for four highly star-forming early-type spirals are presented here, along with H I data for three additional galaxies from other sources. H I maps of six of seven galaxies reveal unambiguous signs of a recent encounter, via tidal tails and H I bridges. Most of these galaxies appear undisturbed in the optical, and these interactions probably would have gone unnoticed without H I mapping. Such high rates of interaction suggest that galactic encounters may play an important role in the evolution of early-type spiral galaxies.
