Tests of General Relativity using black hole X-ray data

Abstract

The theory of General Relativity has successfully passed a large number of observational tests. The theory has been extensively tested in the weak-field regime with experiments in the Solar System and observations of binary pulsars. Recently, there have seen significant advancements in the study of the strong-field regime, which can now be tested with gravitational waves, X-ray data, and mm Very Long Baseline Interferometry observations. Here we summarize the state-of-the-art of the tests of General Relativity with black hole X-ray data, discussing its recent progress and future developments.

“…The theory of General Relativity is well-tested and predicts astrophysical objects and phenomena which observations have confirmed such as the black holes and the gravitational waves [1][2][3]. Successful though General Relativity may be in the description of astrophysical gravitational systems, it is challenged by the analysis of the recent cosmological observations [4][5][6][7][8][9][10].…”
