A study shows the unexpected effect of black holes beyond their own galaxies

These results suggest, then, that there is a particular coupling between the black holes and their galaxies, by which they can expel matter to great distances from the galactic centres, and can even affect the evolution of other nearby galaxies. “So not only can we observe the effects of central black holes on the evolution of galaxies, but our analysis opens the way to understand the details of the interaction”, explains Ignacio Martín Navarro, who is the first author of the article.
