Stellar and Gas Kinematics in the Core and Bar Regions of M100
... We have presented here our preliminary results of M100, taken with the SAURON integral field spectrograph. We have confirmed there are indications for non-circular motions due to spiral armlets and/or the bar. The low dispersion material seen in the gas dispersion map lies where the massive star-for ...
