Featured paperA Unified Model for the Gravitational Wave Background and Quasar Luminosity Functions

Scientists are trying to work out how many giant black holes there are and how fast they eat. They tested a model using clues from waves in space and the bright light made as black holes feed. The model could explain the light without needing the black holes to eat especially fast. That is a promising fit to the clues, not a direct look at each black hole’s meal.
