A SAMI and MaNGA view on the kinematics of star-forming galaxies
We investigate the physical connection between the growth of dispersionsupported stellar structures (e.g. classical bulges) and position of galaxies on the star forming main sequence (SFMS) at z~0. Combining the might of the SAMI and MaNGA galaxy IFS surveys, we measure the λRe spin parameter for 37...
