Modified Virial Formulae and the Theory of Mass Estimators
J. An, N. W. Evans
We show how to estimate the enclosed mass from the observed motions of an ensemble of test particles. Traditionally, this problem has been attacked through virial or projected mass…

Hypervirial Models of Stellar Systems
N. W. Evans, J. An
A family of cusped potential-density pairs is presented for modelling galaxies and dark haloes. The density profile is cusped like 1/r^(2-p) at small radii. The distribution functi…
