Query: Kinematics in the starbursting circumnuclear region of M100   We have obtained integral-field spectroscopic data, using the SAURON
instrument, of the bar and starbursting circumnuclear region in the barred
spiral galaxy M100. From our data we have derived kinematic maps of the mean
velocity and velocity dispersion of the stars and the gas, which we present
here. We have also produced maps of the total, [OIII], and Hbeta intensity. The
gas velocity field shows significant kinematic signatures of gas streaming
along the inner part of the bar, and of density wave streaming motions across
the miniature spiral arms in the nuclear pseudo-ring. The stellar velocity
field shows similar non-circular motions. The gas velocity dispersion is
notably smaller where the star formation occurs in the nuclear zone and HII
regions.
