Up to 10 years ago, the theory of General Relativity was mainly tested in weak gravitational fields with experiments in the Solar System and radio observations of binary pulsars. Stellar-mass black holes were simply dark and compact objects in X-ray binaries with a mass exceeding the maximum mass for neutron stars. Supermassive black holes were dark astrophysical systems in galactic nuclei and they were too massive, compact, and old to be clusters of non-luminous bodies like neutron stars or planets. There was no evidence that the spacetime geometry around these objects was consistent with the Kerr solution of General Relativity. The past 10 years have seen a tremendous progress in this research field and we can now study the spacetime geometry around astrophysical black holes with gravitational waves, X-ray observations, and black hole imaging. The workshop will focus on recent studies to test the nature of astrophysical black holes and to use these objects as laboratories to discover new physics. 

The workshop will be in Room C101, Physics Research Building, Jiangwan Campus. Non-Fudan participants will stay at the Fengjing Hotel, which is close to Exit 7 of Xinjiangwancheng Station and at walking distance from the Physics Research Building.
