In the context of galaxy formation and dark matter halos, the virial mass is defined as the mass enclosed within the virial radius r v i r of a gravitationally bound system, a radius within which the system obeys the virial theorem. The virial radius is determined using a "top-hat" model. A spherical "top hat" density perturbation destined to become a galaxy begins t
