Baryonic Tully–Fisher relation (left panel) and the analogue of the Tully–Fisher relation for ETGs (right panel). Left panel: Baryonic mass and the circular speed on the flat region of the rotation curves of local disc galaxies and the best-fit BTFR relation in blue (Lelli et al. 2016b). Right panel: stellar masses and inner rotation of local ETGs with stellar kinematics in purple (Lelli et al. 2017) and with inner CO rotating discs in violet (Davis et al. 2016). We show the baryonic mass and external circular speed of our sample according to the legend, in the right panel, we also show their stellar mass (stars).
