Intrinsic errors of the central galactic mass derived from rotation curves under the influence of a weak non-axisymmetric potential

Abstract

Rotation curves are often used to estimate the mass distribution of spiral galaxies, assuming that the circular velocities of the interstellar medium balance with the galactic centrifugal force. However, non-circular motions caused by a non-axisymmetric gravitational potential, such as a stellar bar, may disturb the velocity field, resulting in errors in… (More)
