Studies of black holes and wormholes with Millimetron observatory: VLBI capabilities and simulations
Abstract
Key science case for the Millimetron Space Observatory (MSO) in VLBI mode is the general theory of relativity (GR) verification and the studying of physical processes in an extremely strong gravitational field. MSO, as a part of the space-ground interferometer (S-VLBI), makes it possible to achieve high angular resolution necessary to detailed studies of the space-time structure and physical processes in the vicinity of the event horizon of supermassive black holes in our Galaxy and in the M87 galaxy. The space-ground interferometer will make it possible to study the brightness distribution in the accretion disk and the structure of the photon ring. Supermassive black holes with masses reaching many billions of solar masses are also found in active galactic nuclei (AGN). Some of these objects may be targets of the MSO S-VLBI program. The Millimetron mission will also search for hypothetical wormholes. This task involves testing the hypothesis that the nuclei of some galaxies can be wormholes, not supermassive black holes, using the observational properties of wormholes that differ from black holes. It is important to note that the search for wormholes does not require additional observational time. These studies will be conducted as a part of the black holes observations. This report describes the main parameters and capabilities of the Millimetron space-ground interferometer, which, in combination with numerical simulation of multidimensional relativistic magnetohydrodynamic flows in curved space-time, will allow this class of problems to be addressed.
