Scalar shortcut to beyond-Kerr ringdown tests and their complementarity with black-hole shadow observations
The episode discusses a paper by Pani and Sanna regarding 'Scalar shortcut to beyond-Kerr ringdown tests and their complementarity with black-hole shadow observations.' The hosts explain how linking these two measurements creates a mathematical bridge, allowing researchers to use gravitational wave ringdown data and black hole shadow data together to test gravity more robustly than using either alone.
