# Relating black hole shadow to quasinormal modes for rotating black holes

@article{Yang2021RelatingBH, title={Relating black hole shadow to quasinormal modes for rotating black holes}, author={Huan Yang}, journal={Physical Review D}, year={2021}, volume={103} }

In this work, we explore the connection between the critical curves ("shadows") and the quasinormal mode frequencies (in the eikonal limit) of Kerr black holes. This mapping has been previously established for non-rotating black holes. We show that, the shadow seen by an distant observer at a given inclination angle, can be mapped to a family of quasinormal modes with $m/(\ell+1/2)$ bounded within certain range, where $m$ is is azimuthal node number and $\ell$ is the angular node number. We…

It is shown analytically that spacetimes that deviate from the Kerr metric but satisfy weak-field tests can lead to large deviations in the predicted black-hole shadows that are inconsistent with even the current EHT measurements.
