Mind the Resonances: Final stages of accretion into bumpy black holes

TL;DR

This paper proposes a method to test the Kerr black hole hypothesis by analyzing electromagnetic signals from accretion disks around bumpy black holes, focusing on chaotic motion signatures.

Contribution

It introduces a novel approach linking chaotic accretion disk phenomena to potential observational tests of black hole geometry.

Findings

Chaotic motion influences electromagnetic spectra.

Potential observational signatures of bumpy black holes.

Framework for testing black hole deviations from Kerr.

Abstract

In this article we discuss a possible way of testing the Kerr black hole hypothesis by taking advantage of phenomena correlated with chaotic motion in the final stages of an accretion disk around a bumpy black hole. We anticipate that these phenomena should have an imprint in the electromagnetic spectrum coming from the accretion disk.
