This led to the discovery of a point source supermassive object named Sagittarius A* (Sgr A*) whose inferred mass is ~ 4 million solar masses. Thanks to the precise tracking of the motion of stars in its surroundings and the direct imaging of accre ting matter in this region\, we can now unambiguously identify this object as a supermassive black-hole (SMBH). A promising possibility to reach new experimental frontiers in black hole physics is the existence of detectab le pulsars on tight relativistic orbits in the Galactic Center. While\, up to date\, no pulsar has been directly observed in orbit around Sgr A*\, f uture observing facilities like the Square Kilometer Array (SKA) promise n ot only to reach this goal\, but also to be able to perform timing analysi s of such sources. In this talk I will show the recent progress in the mod eling of pulsar timing in the Galactic Center and the avenues that the suc cessful detection of a pulsar in this environment would open for unparalle led tests of gravity.

The centre of the Milky Way has been subject of an intense observational program over the pa st thirty years. This led to the discovery of a point source supermassive object named Sagittarius A* (Sgr A*) whose inferred mass is ~ 4 million so lar masses.

Thanks to the precise tracking of the motion of star s in its surroundings and the direct imaging of accreting matter in this r egion\, we can now unambiguously identify this object as a supermassive bl ack-hole (SMBH). A promising possibility to reach new experimental frontie rs in black hole physics is the existence of detectable pulsars on tight r elativistic orbits in the Galactic Center.

While\, up to date\, no pulsar has been directly observed in orbit around Sgr A*\, future obser ving facilities like the Square Kilometer Array (SKA) promise not only to reach this goal\, but also to be able to perform timing analysis of such s ources. In this talk I will show the recent progress in the modeling of pu lsar timing in the Galactic Center and the avenues that the successful det ection of a pulsar in this environment would open for unparalleled tests o f gravity.
