The Galactic halo of mass ~ 2 x 10^12 Msol 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 x 10^6 Msol within a minimal radius of ~ 18 mpc for fermin masses ~ 15 keV.13 pages, 3 figures, equations simplified, Fig. 1 slightly changed, summary expanded, 6 new references addedAstrophysicsHigh Energy Physics - Phenomenologytext
