The SAMI Galaxy Survey: the contribution of different kinematic classes to the stellar mass function of nearby galaxies
We use the complete Sydney-AAO Multi-object Integral field spectrograph (SAMI) Galaxy Survey to determine the contribution of slow rotators (SRs), as well as different types of fast rotators (FRs), to the stellar mass function of galaxies in the local Universe. We use stellar kinematics not only to...
