The nature of hypermassive objects at the center of M87 and the Milky Way

Résumé

Focusing on the Sgr A* and M87 images of hypermassive objects at the center of M87, we note a divergence from an identification with images of giant black holes, as well as the identity, in both cases, of the value 3, representing the ratio of maximum to minimum temperature. It is suggested that these are subcritical objects, where the darkening of their central part derives from the fact that their radius is (8/9)1/2 Rs. Under these conditions, a very strong pressure gradient can oppose the force of gravity. We suggest a scheme for the formation of your objects.
