Something pushed supermassive object off a galaxy's bull's-eye
MIAMI — Supermassive black holes are shiftier beasts than astronomers suspected. A new analysis reveals that the giant black hole at the core of the highly studied galaxy M87 somehow got displaced about 22 light-years from the galaxy’s center.
“This result signals a necessary shift in the supermassive black hole paradigm,” said Daniel Batcheldor of the Florida Institute of Technology in Melbourne. The prevalence of off-center black holes “could represent a significant change in our understanding of supermassive black holes, galaxies and the ways in which they may interact with each other,” he added.
