We summarize the present status of VLBI experiments at 3 mm (8 6 GHz), 2 mm (129-150 GHz) and 1.3 mm (215230 GHz). We present and discuss a new 3 mm VLBI map of M 87, whic h as a spatial resolution of only ∼ 20 Schwarzschild radii. We discuss recent results for Sgr A* and argue in favor of new observations within an extended European mm-VLBI network, in order to search for variability. We discuss the p ossibilities to image the ‘event horizon’ of a super-massiv e black hole at wavelengths< 2 mm… CONTINUE READING
