The SAMI Galaxy Survey:kinematic alignments of early-type galaxies in A119 and A168
We investigate the kinematic alignments of luminous early-type galaxies (M r ≤ -19.5 mag) in A119 and A168 using the kinematic position angles () from the Sydney-AAO Multi-object Integral-field spectrograph (SAMI) survey data, motivated by the implication of the galaxy spin alignment in a cosmologic...
