The ALMaQUEST Survey. VIII. What causes the discrepancy in the velocity between the CO and H alpha rotation curves in galaxies?

We compare the CO(1-0) and Hα kinematics in 34 nearby galaxies, selected from the ALMaQUEST and EDGE-CALIFA surveys. We use 3D-Barolo, a 3D tilted-ring model, to derive the CO and Hα rotation curves. Before comparing rotation curves in the 34 nearby galaxies, we found systematics...
