Game changer



The finding "is important for how black holes relate to galaxies," said team member Jens Thomas of the Max Planck Institute for Extraterrestrial Physics in Germany. "If you change the mass of the black hole, you change how the black hole relates to the galaxy."


Because of this relationship, the revised mass could impact astronomers' theories of how galaxies grow and form.


Higher black hole masses could also solve a paradox of the masses of faraway, developing galaxies called quasars. These mysterious denizens of the early universe are very bright, developing galaxies with black holes surrounded by gas and dust, all rife with star formation. Quasars are colossal, around 10 billion solar masses, "but in local galaxies, we never saw black holes that massive, not nearly," Gebhardt said.


"The suspicion was before that the quasar masses were wrong," he said. But "if we increase the mass of M87 two or three times, the problem almost goes away."
