Descripción
Two-dimensional maps of the stellar and gas kinematics of the bar and
starbursting circumnuclear region in the barred spiral galaxy M100 are
presented. In this progress report, we present maps of the total
intensity, mean velocity and velocity dispersion for the stars and the
gas. The gas velocity field shows significant kinematic signatures of
gas streaming along the inner part of the bar, and across the miniature
spiral arms in the nuclear pseudo-ring. The stellar velocity field,
presented here for the first time, also shows non-circular motions. The
gas velocity dispersion is notably smaller where the star formation
occurs in the nuclear zone and HII regions. We outline our further plans
with the data set.
