Wandering black holes may hold clues to how galaxies assembled
Yale News reports that galactic mergers can push black holes away from galaxy centers, especially in smaller galaxies. A simulation suggests their locations may preserve clues to those galaxies’ histories.
TLDR
Yale News reports that researchers used the ASTRID simulation to trace galaxies over about 12.6 billion years. In low-mass galaxies, the share hosting wandering black holes rose toward the present while the share hosting central black holes fell, according to the study. The researchers say comparing the two groups could help separate clues about how black holes first formed from clues about how their galaxies assembled.
