How a dust concentration mimics dynamical signatures around the nucleus of NGC 7331.
Where the pheonomenon of wavelength-dependent kinematics has been observed in galaxies, it has been well modelled as a dust extinction effect. Therefore "compact mass features" in rotation curves close to the nuclei of dusty inclined galaxies may not be caused by dynamical effects, but by differential extinction by circumnuclear dust.
