Marscher and Svetlana Jorstad, a BU senior research scientist and a contributor to the paper, were part of the team that worked on the first attempts at imaging Sgr A*, and were both heavily involved in the first-ever images captured of a black hole in Messier 87 (M87), a galaxy about 55 million light-years from Earth. The findings were published in a special issue of The Astrophysical Journal Letters. The image was produced by a global research team called Event Horizon Telescope (EHT) Collaboration, which used observations from a worldwide network of radio telescopes. “The four-million solar-mass ‘monster’ at the center of our galaxy is indeed a black hole,” says Alan Marscher, a BU College of Arts & Sciences professor of astronomy, who is one of over 300 contributors to the breakthrough. The revelatory image is of Sagittarius A*, or Sgr A*, a black hole with a mass four million times that of the sun and located about 27,000 light-years away.
It’s a first for our galaxy-we now have a picture of the black hole that exists at the center of the Milky Way.
