In this paper, we undertake a comprehensive examination of quasinormal modes (QNMs) linked to Morris-Thorne, also known as Bronnikov-Ellis wormholes, delving into scalar, electromagnetic, and gravitational perturbations using the spectral method. Our research corrects inaccuracies previously reported in the literature and addresses areas where the Wentzel--Kramers--Brillouin (WKB) approximation proves inadequate. Moreover, we introduce and evaluate a novel spectral technique designed to consolidate recent advancements in formulating QNM boundary conditions at both the wormhole throat and space-like infinity. This innovative approach bridges critical gaps in existing methodologies and enhances the accuracy and applicability of QNM analysis in the study of wormhole physics.

  1. Quasinormal modes and grey-body factors of Morris-Thorne wormholes

    gr-qc 2024-12 reject novelty 6.0 of 10

    Sixth-order WKB formulas for wormhole quasinormal modes and grey-body factors are presented, but the grey-body factor part is internally inconsistent.

  2. Correspondence between quasinormal modes and grey-body factors of spherically symmetric traversable wormholes

    gr-qc 2024-12 conditional novelty 4.0 of 10

    For three families of traversable wormholes, the authors verify that the WKB correspondence between quasinormal modes and grey-body factors, known for black holes, holds to second order beyond the eikonal limit.
