Observed Velocity Field in a Galaxy (Simulation)

The image reveals a computer simulation of the velocity field in a galaxy, as deduced on the basis of IFU spectra. The blue area has negative velocities and is thus the approaching side of the galaxy, while the red area is receding. In this way, the direction of rotation can be determined. The velocity unit is km/s.
