"Simulations foresee hordes of colliding black holes in observatory's future" by Steve Koppes, UChicago News
"The main thing we find is that what LIGO detected makes sense," said Daniel Holz, KICP senior member and a co-author of the Nature paper. The simulations predict the formation of black-hole binary stars in a range of masses that includes the two already observed. As more LIGO data become available, Holz and his colleagues will be able to test their results more rigorously.
