TL;DR: The first Event Horizon Telescope (EHT) observations of Sagittarius A* (Sgr A*), the Galactic center source associated with a supermassive black hole, were conducted in 2017 using a global interferometric array of eight telescopes operating at a wavelength of 1.3 mm as mentioned in this paper .

TL;DR: In this article , the authors calibrate the relationship between the geometrically defined black hole shadow and the observed size of the ring-like images using a library that includes both Kerr and non-Kerr simulations.
