Astrophysical black holes are expected to be described by the Kerr metric. This is the only
stationary, vacuum, axisymmetric metric, without electromagnetic charge, that satisfies
Einstein's equations and does not have pathologies outside of the event horizon. We
present new constraints on potential deviations from the Kerr prediction based on 2017 EHT
observations of Sagittarius A*(Sgr A*). We calibrate the relationship between the
geometrically defined black hole shadow and the observed size of the ring-like images�…
