Circular velocities of thick galaxy disks

Project description

vcdisk: Rotation curves of thick galaxy disks

A minimal python module to solve Poisson's equation in a thick galactic disk. This is useful to compute the circular velocity on the disk plane of a galaxy with observed surface density profile and arbitrary, user-defined vertical profile.

vcdisk implements the algorithm of Casertano (1983), which calculates the radial force on the disk plane as a 2-D integral (their Eq. 4) and then derives the velocity of a circular orbit on the disk plane.
