Results based on data obtained with the 4-station Event Horizon Telescope back in 2013 were published in a peer-reviewed journal, showing tantalizing, but not yet conclusive, structure in Sgr A* on the scale of about 3 Schwarzschild radii of the black hole. This was the first time that the APEX telescope joined the EHT array as the first mm-wave Very Long Baseline Array (VLBI) station in the southern hemisphere.
