An article published in the journal “Physical Review Letters” describes the simulations of the evolution of globular clusters of the type commonly found in galaxies to assess the possibility of black holes mergers. A team led by MIT astrophysicist Carl Rodriguez used the Quest supercomputer at Northwestern University to simulate 24 clusters with different characteristics, also calculating relativistic effects, concluding that repeated mergers can occur, forming black holes more massive than the stellar ones.
