Interactions between massive galaxies and their satellites: probing galaxy mass distribution.
Using the measured common distance from the observer, angular separation of a dwarf satellite from its mother galaxy and their relative radial velocities, plus three criticable assumptions: circularity of the orbit, spherical symmetry of the gravitational potential, and that the radius of the dwarf galaxy is limited by tidal interaction with the
