Simulations indicate that Milky Way galaxy may have up to 2000 black holes in its halo

by Bob Yirka

Valery Rashkov and Piero Madau, space scientists with the University of California have uploaded a paper to the preprint server arXiv in which they suggest that the Milky Way galaxy likely has between 70 and 2000 intermediate-mass black holes (IMBHs) existing in its outer edges. They came to this conclusion by building a computer model that mimics what they believe occurred when galaxies, and by extension, black holes merged during their formative years.

In building their simulation, the researchers began with the idea that when galaxies form, they have a “seed” black hole at their center. Over time, they suggest, some early galaxies ran into one another, merging as they did so, causing the black holes at their respective centers to merge as well. But not all couplings worked out, their simulations show. Because of gravitational waves created by such collisions, smaller black holes could be ejected, and would as a result, travel all the way to the outer reaches of the galaxy where they would reside alone in space…
