LIGOs Twin Black Holes Might Have Been Born Inside A Single Star

On September 14, 2015, the Laser Interferometer Gravitational-wave Observatory (LIGO) detected gravitational waves from the merger of two black holes 29 and 36 times the mass of the Sun. Such an event is expected to be dark, but the Fermi Space Telescope detected a gamma-ray burst just a fraction of a second after LIGO's signal. New research suggests that the two black holes might have resided inside a single, massive star whose death generated the gamma-ray burst.

'Mosh pits' in star clusters a likely source of LIGO's first black holes
Astrophysicists have shown their theoretical predictions last year were correct: The merger of two massive black holes detected Sept. 14, 2015, could easily have formed through dynamic interactions in the star-dense core of a globular cluster. These binary black holes are born in the cluster's chaotic 'mosh pit,' kicked out of the cluster and then eventually merge into one black hole. LIGO's first detection of colliding black holes is perfectly consistent with their model. Ref. Source 9t.
