A fixed point for black hole distributions

Understand

Understanding distributions of black holes is crucial to both astrophysics and quantum gravity.

• Studying astrophysical population statistics has even been suggested as a channel to constrain black hole formation from the quantum vacuum.
• Here we propose a Gedankenexperiment to show that the non-linear properties of binary mergers (simulated with accurate surrogate models) generate an attractor in the space of distributions.
• Our results show that the joint distribution of spin magnitude and fractional mass loss evolves to a fixed point, converging in a few generations.
