... Захаров А. Ф. It is generally accepted now that there is a supermassive black hole at the Galactic Center. ... Observations of trajectories of bright stars at the Galactic Center in IR band have been done with an enormous precision. ... We review theoretical studies and their links with observations to get constraints on parameters of the Galactic Center potential and as a result to evaluate parameters of the black hole and distributions of stellar cluster and dark matter near the black hole. ...

... GCR and SCR are primary cosmic rays. 10-15 years after the discovery of cosmic radiation (1919) there emerged two main avenues of investigation in the physics of cosmic rays (CR): 1) nuclear - elucidation of the origin of elementary particles and nuclear interactions; and 2) astrophysical (space physics) - solution of the problem related to the origin and variations (changes in intensity) of CR. ... Besides, the CR flux in interplanetary space is, strictly speaking, not isotropic. ...
