Descripción
We give two examples of spiral galaxies that show non-circular gas
motions in the inner kiloparsecs, from SAURON integral field
spectroscopy. We use harmonic decomposition of the velocity field of the
ionized gas to study the underlying mass distribution, employing linear
theory. The higher order harmonic terms and the main kinematic features
of the observed data are consistent with an analytically constructed
simple bar model. We also present maps of a number of strong absorption
lines in M 100, derive simple stellar populations and correlate them
with features in the gas kinematics.
