Astronomers are announcing today that they have discovered 33 pairs of waltzing black holes in distant galaxies. This result was presented by Dr. Julia Comerford of the University of California, Berkeley in Berkeley, California to the American Astronomical Society meeting in Washington, DC. This result is particularly important because it shows that supermassive black hole pairs are more common than previously known from observations, and because the black hole pairs can be used to estimate...
