Scientific paper

The authors report kinematic and imaging observations of NGC 2110 and find that the interstellar gas is orbiting with projected rotation axis parallel to the minor axis of the stellar light. The rotation curve is steep close to the center and flat farther out. However, the nucleus is displaced by ≡220 pc from the apparent mass center of the galaxy. This last result is discussed in terms of models invoking differential obscuration of stars and gas, non-Keplerian motion of the gas, or a large mass of unseen material which dominates the rotation curve.
