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.
