abstract

The recently proved `no short hair' theorem asserts that, if a spherically-symmetric static black hole has hair, then this hair (the external fields) must extend beyond the null circular geodesic (the "photonsphere") of the corresponding black-hole spacetime: $r_{\text{field}}>r_{\text{null}}$. In this paper we provide compelling evidence that the bound can be {\it violated} by {\it non}-spherically symmetric hairy black-hole configurations. To that end, we analytically explore the physical properties of cloudy Kerr-Newman black-hole spacetimes -- charged rotating black holes which support linearized stationary charged scalar configurations in their exterior regions.

Distorting Kerr Images with Parity-Odd Scalar Hair

gr-qc · 2026-05-27 · unverdicted · novelty 5.0

Numerical study of thin accretion disk images shows that increasing parity-odd scalar hair on Kerr black holes shrinks and distorts the photon ring and shadow, producing multiple disconnected shadows and chaotic lensing features in strong-hair regimes.
