Probing General Relativity with the Event Horizon Telescope
The first resolved images of the strong-gravity region of a black hole will soon be produced by the Event Horizon Telescope (EHT). I will discuss the significant instrumental, observational, and theoretical efforts of the EHT collaboration that have come together in order to probe the strong-field gravity regime of the black hole in the center of our Galaxy in SgrA* and in the galaxy M87. I will highlight the challenges of interpreting past and future observations, which require state-of-the-art computational physics simulations of the plasma, black hole, and the polarized radiation. Such simulation models reveal a wealth of information that can be used to probe (and potentially test) Einstein's general relativity in the strong-field regime.
