Image Details
Caption: Figure 9.
(left) Stellar kinematics (SK), and (center) Hα gas kinematics (GK) velocity maps. There are two galaxies per row. Labels indicate the PA with error and S/N within one effective radius. Circle indicates the 15″ size of the SAMI hexabundle. (right) Smoothed map of the GK, including labels with the GAMA ID, δPA, sSFR, and the group magnitude gap and BGG offset. Dashed circle indicates the effective radius (Re). Bottom right corner shows an inset image of a postage stamp in r-band from the GAMA Panchromatic Swarp Imager (PSI) with 20″ side length (note that inset image is on a very different scale from the SAMI images). Red and blue dashed lines show the major axes of rotation for stellar and gas kinematics, respectively.
