Scientists can also do reverberation mapping, which uses X-ray telescopes to look for time differences between emissions from various
locations near the black hole to understand the orbits of gas and photons around the black hole.
The American, Korean and Australian partners involved with the GMT will take advantage of the telescope's Southern Hemisphere
location to study the otherwise hidden Large and Small Magellanic Clouds — two of the Milky Way's
nearest neighbor galaxies — and the
black hole in the center of our galaxy.
