Black holes may grow quietly alongside galaxies even without violent mergers

Scientists studying 2,435 galaxies found that even those lacking a central stellar bulge can grow active black holes at the same rate as others. This suggests that the growth of black holes is not dependent on galaxy mergers, which were previously thought to be necessary for this process.
