Abstract:
We present major and minor-axis kinematics of stars and ionized gas as
well as narrow and broad-band surface photometry of the Sa spiral NGC
2855. In the nuclear regions of this unbarred and apparently
undisturbed spiral galaxy the gas is rotating perpendicularly to the
galaxy disk. We suggest that this kinematically-decoupled component is
the signature of an acquisition process in the history of this galaxy.
