Echoes from braneworld wormholes

We have studied the stability of wormhole geometries, under massless scalar, electromagnetic, and axial gravitational perturbations, in context higher dimensional spacetimes. Intriguingly, construction a spacetime presence dimensions, known as braneworld wormholes, does not require existence exotic matter fields, unlike scenario four dimensions. Being nonvacuum spacetime, effective potential experienced by perturbation differs considerably from scenarios involving black holes. In particular, present work provides one first attempts to study perturbations Our analysis, both analytical numerical techniques, demonstrates that there are echoes time domain signal all echo delay is intimately related parameters originating Thereby combining attempt search for wormholes extra with wave echoes. Implications future directions also been discussed.
