Using Pulsars to Map the Milky Way's Black Hole

The BlackHoleCam initiative has tested the Theory of General Relativity by observing pulsars orbiting Sagittarius A*, the supermassive black hole at the center of the Milky Way. The initiative aims to use the largest and most sensitive telescopes in the world, including the Atacama Large Millimeter/submillimeter Array (ALMA) and the Caltech Submillimeter Observatory (CSO), to spot binary pulsars orbiting Sag A*. The same technology used to snap the first image of Sag A* will be used to spot binary pulsars orbiting it, using Very Long Baseline Interferometry (VLBI).
