The Disk and Dark Halo Mass of the Barred Galaxy NGC 4123. II. Fluid‐Dynamical Models
The Disk and Dark Halo Mass of the Barred Galaxy NGC 4123. II. Fluid‐Dynamical Models
We report a dynamical determination of the separate contributions of disk and dark halo masses to the rotation curve of a spiral galaxy. We use fluid-dynamical models of gas flow in the barred galaxy NGC 4123 to constrain the dynamical properties of the galaxy: disk M/L, bar pattern speed, and …
