Description
This presentation outlines recent theoretical and observational advances in exploring wormhole spacetimes through high-frequency quasiperiodic oscillations (QPOs). It briefly reviews the motivation for wormholes as potential black hole mimickers and summarises key models—from scalar-field-driven solutions to Einstein–Dirac–Maxwell systems and Reissner–Nordström-based wormholes in braneworld scenarios. Emphasis is placed on the role of QPO signatures, alongside spectral and imaging data (notably from the EHT), in constraining or distinguishing these exotic geometries from standard black holes. Finally, compiled results illustrate how dedicated QPO modelling may offer indirect evidence pointing toward wormhole-like solutions, complementing other observational tests in the quest to distinguish wormholes from standard black holes.
