Contribution

It establishes a new spectral correspondence for traversable wormholes, expanding the understanding of their physical properties.

Findings

Confirmed the correspondence for various wormhole models

Extended spectral relations known for black holes to wormholes

Validated the theoretical link with multiple examples

Abstract

A correspondence between two distinct spectral problems, quasinormal modes and grey-body factors, has recently been established for a wide class of black holes. Here, we demonstrate that a similar correspondence exists for a broad class of traversable wormholes and verify it using several well-known examples.
