Modeling vertical structure in circular velocity of spiral galaxy NGC 4244
arXiv:1504.05903 · doi:10.1093/mnras/stv1163
Abstract
We study the vertical gradient in azimuthal velocity of spiral galaxy NGC 4244 in a thin disk model. With surface density accounting for the rotation curve, we model the gradient properties in the approximation of quasi-circular orbits and find the predictions to be consistent with the gradient properties inferred from measurements. This consistency may suggest that the mass distribution in this galaxy is flattened.
