Research Suggests Possible Black Hole Merger

Researchers at Middlebury College think that they’ve found a pair of black holes which are circling one another:

Glikman, the P. Frank Winkler fellow in physics at Middlebury and an assistant professor in the Department of Physics, studies quasars – galaxies with active black holes at their center – and their role in the formation and evolution of the universe. Her expertise at analyzing data sets on quasar variability helped produce the recent findings published on January 7, 2015, in the journal Nature.

The black holes in PG 1302-102, which are less than a light year apart, demonstrate “a strong, smooth periodic signal of optical variability” every 5.5 years, which suggests that the pair could be in the final stages of a merger.
