Astronomers Capture Orbital Motion Around a Black Hole With Unprecedented Clarity

Aug 07, 2019
“Previous studies have demonstrated ALMA's ability to detect rotating gas disks near a black hole and even to measure black hole masses in a few cases. For the first time, however, these observations highly resolve cold gas rotation within what is called the sphere of influence — the innermost region of the galaxy where a black hole's gravity is the dominant force.”
