The formation of S0 galaxies: evidence from globular clusters

Aims.We devise a simple experiment to test the theory that lenticular (S0) galaxies form from spirals whose star formation has been shut down. An individual galaxy's fading is measured using the globular cluster specific frequency (SN), defined as the number of globular clusters normalised by t...
