Abstract:
We consider a self-gravitating ideal
fermion gas at nonzero temperature as a model for the
Galactic halo.
The Galactic halo of mass
2 * 1012 M_o enclosed within
a radius of 200
kpc implies the existence of a
supermassive compact dark object at
the Galactic center that is in hydrostatic and
thermal equilibrium with the halo.
The central object has a maximal mass of 2.3 * 106
M_o within a minimal radius of 18 mpc for
fermion masses 15 keV.
