Scientific paper

NGC 5982 is known to be one of those elliptical galaxies that have peculiar kinematics in their centres. In this paper, optical spectroscopic observations are presented, which show that a specific feature is present in the velocity field of NGC 5982. This suggests that the kinematical behaviour is the result of projection effects in a dynamically smooth triaxial elliptical galaxy, and that it is not due to a dynamically distinct, central mass component. Nevertheless, we suggest that it may be related to a merger event.
