Kinematics of the RRLs from this study. Top panel: rotation curve of the bulge-confined RRLs of our sample (red). The metal-poor (blue) and metal-rich (orange) rotation curves from Rojas-Arriagada et al. (2020) for giant stars are also presented for comparison. The rotation curve of all the RRLs of this study is included in grey. The bulge RRLs rotate more slowly than the metal-rich giants and are related to the metal-poor population. Bottom panel: velocity dispersion curves of the bulge RRLs (red) and the bulge giants. The velocity dispersion for all the RRLs is included in grey.
