Capturing the Echoes of Black Holes with Mathematical Precision

A research group including Ryo Namba (Senior Research Scientist, iTHEMS) has successfully demonstrated a method that systematically and precisely captures the frequency structure of rapidly decaying quasinormal modes of black holes by incorporating the mathematical technique known as exact WKB analysis.

This result enables more rigorous analysis of gravitational wave signals from black holes in various theoretical models and is expected to contribute to improving the precision of future gravitational wave observations and verifying the fundamental properties of black holes with greater accuracy.
