Signals from the horizon: General Relativity and the strong field gravity regime

Andrea Maselli, University Tübingen, Germany

Future gravitational and electromagnetic observations will shed new light on the nature of gravity in the high curvature regime, which has been poorly explored so far. Black holes are among the most genuine strong field predictions of General Relativity, and therefore they represent the ideal candidates to test the pillars of Einstein’s theory. In this talk I will analyze some prospects and strategies developed to test gravity through gravitational waves and electromagnetic signals, produced by binary and isolated astrophysical black holes. In particular I will focus on the constraints that such observations, supplied by current and future experiments, will be able to set on alternative theories of gravity.
