Unraveling the Mystery of a Runaway Supermassive Black Hole.

A 200,000-light-year-long chain of stars believed to be trailing a runaway black hole may actually be a galaxy without a bulge seen edge-on, according to researchers at the Instituto de Astrofisica de Canarias. The team compared the supposed tail of stars to a well-studied bulge-less galaxy called IC5249 and found that the observations of the two different objects were in surprising agreement. The team's research has been accepted for publication in the journal Astronomy and Astrophysics.
