Can fermionic dark matter mimic supermassive black holes?
  We analyze the intriguing possibility to explain both dark mass components in
a galaxy: the dark matter (DM) halo and the supermassive dark compact object
lying at the center, by a unified approach in terms of a quasi-relaxed system
of massive, neutral fermions in general relativity. The solutions to the mass
distribution of such a model that fulfill realistic halo boundary conditions
inferred from observations, develop a highly-density core supported by the
fermion degeneracy pressure able to mimic massive black holes at the center of
galaxies. Remarkably, these dense core-diluted halo configurations can explain
the dynamics of the closest stars around Milky Way's center (SgrA*) all the way
to the halo rotation curve, without spoiling the baryonic bulge-disk
components, for a narrow particle mass range $mc^2 \sim 10$-$10^2$~keV.
