Whirling orbits around twirling black holes from conformal symmetry

Understand

Dynamics in the throat of rapidly rotating Kerr black holes is governed by an emergent near-horizon conformal symmetry.

• The throat contains unstable circular orbits at radii extending from the ISCO down to the light ring.
• We show that they are related by conformal transformations to physical plunges and osculating trajectories.
• These orbits have angular momentum arbitrarily higher than that of ISCO.
