Tests of Gravitational Theories with Observations of the Galactic Center and the Center of the Galaxy M87

摘要

In October 2019, the Nobel Prize in Physics was awarded "for contributions to our understanding of the evolution of the universe and Earth's place in the cosmos." In particular, one half of the prize was awarded to James Peebles "for theoretical discoveries in physical cosmology"; the other half of the prize was shared between Michel Mayor and Didier Queloz "for the discovery of an exoplanet orbiting a solar-type star." In fact, this also means recognition of the importance of work in the field of gravity, astrophysics, and cosmology. The use of astronomical observations of the Galactic Center to obtain constraints on the gravitational field near a supermassive black hole is discussed.
