Summary

ROCHESTER, NEW YORK-- The origin of massive black holes and the galaxies that surround them is a chicken-and-egg conundrum. Now, researchers reported here last week at a meeting of the American Astronomical Society that giant black holes and their host galaxies appear to be cosmic siblings that grew up at the same time. That conclusion rests on a newly unveiled relationship between the masses of black holes and how tightly gravity binds together the billions of stars around them.
