Query: Empirical testing of Tsallis' Thermodynamics as a model for dark matter
  halos   We study a dark matter halo model from two points of view: the ``stellar
polytrope'' (SP) model coming from Tsallis' thermodynamics, and the one coming
from the Navarro-Frenk-White (NFW) paradigm. We make an appropriate comparison
between both halo models and analyzing the relations between the global
physical parameters of observed galactic disks, coming from a sample of actual
galaxies, with the ones of the unobserved dark matter halos, we conclude that
the SP model is favored over the NFW model in such a comparison.
