Shadows near supermassive black holes: from a theoretical concept to GR test
Alexander F. Zakharov
General relativity (GR) passed many astronomical tests but in majority of them GR predictions have been tested in a weak gravitational field approximation. Around 50 years ago a sh…

Improvement of graviton mass constraints using GRAVITY's detection of Schwarzschild precession in the orbit of S2 star around the Galactic Center
Predrag Jovanović, Vesna Borka Jovanović, Duško Borka +1
Here we study possible improvements of the existing constraints on the upper bound of graviton mass by the analysis of the stellar orbits around the SMBH at the GC in the framework…
