The Spitzer Interacting Galaxies Survey: An Infrared Atlas of Interacting Galaxies

Astronomers from the Harvard-Smithsonian Center for Astrophysics report that, when compared with non-interacting field galaxies, the star formation rate does indeed increase in merging spirals, but that the efficiency of star formation does not appear to increase much as the merger progresses, at least in this limited sample. Most galaxies, including our own Milky Way, […]
