X-Ray Tests of General Relativity with Black Holes

Understand

General relativity is one of the pillars of modern physics.

• For decades, the theory has been mainly tested in the weak field regime with experiments in the Solar System and radio observations of binary pulsars.
• Until 2015, the strong field regime was almost completely unexplored.
• Thanks to new observational facilities, the situation has dramatically changed in the last few years.
