In 2018, this enabled Eisenhauer and colleagues to detect, in particular, the

Since 2005, Eisenhauer has been principal investigator of the GRAVITY experiment, which connects the
European Southern Observatory's four Very Large Telescopes in Paranal, Chile, together as stellar interferometers, achieving an angular resolution equivalent to that of a 130-metre diameter telescope.
