There are many mechanisms by which galaxies can transform from blue, star-forming spirals, to red, quiescent
early-type galaxies, but our current census of them does not form a complete picture. Recent observations of
nearby case studies have identified a population of galaxies that quench “quietly.” Traditional poststarburst
searches seem to catch galaxies only after they have quenched and transformed, and thus miss any objects with
additional ionization mechanisms exciting the remaining...[Show more]
