Query: Simulated Dark-Matter Halos as a Test of Nonextensive Statistical
  Mechanics   In the framework of nonextensive statistical mechanics, the equilibrium
structures of astrophysical self-gravitating systems are stellar polytropes,
parameterized by the polytropic index n. By careful comparison to the
structures of simulated dark-matter halos we find that the density profiles, as
well as other fundamental properties, of stellar polytropes are inconsistent
with simulations for any value of n. This result suggests the need to
reconsider the applicability of nonextensive statistical mechanics (in its
simplest form) to equilibrium self-gravitating systems.
