New research probes the merger history of black hole mergers in the Milky Way.

Astronomers think that supermassive black holes likely sit at the center of all large galaxies.

They know of about 50 candidate or confirmed stellar mass black holes with tens of solar masses.

The researchers searched for ejected stars by filtering for both velocity and metallicity.

This rate is in line with what's expected to come from stars disrupted by Hills mechanism alone.

"Our results can be used to constrain ejection mechanisms," the authors write.

"We expect that our non-detection of a population of bound ejecta constrains the merger history of Sgr A star".
