Black holes in degenerate Einstein Gauss-Bonnet gravity: Can QNMs distinguish them from GR?
Suvikranth Gera, Poulami Dutta Roy
In this study, for the first time, we analyse the quasinormal modes of black holes occurring within the framework of degenerate gravity. We investigate the properties of the asympt…

Novel triple barrier potential for axial gravitational perturbations of a family of Lorentzian wormholes
Poulami Dutta Roy
We study the behavior of a specific Lorentzian wormhole family under gravitational perturbations. In earlier work [EPJC 80, 850 (2020)], we have proved the stability of a test scal…

Revisiting a family of wormholes: geometry, matter, scalar quasinormal modes and echoes
Poulami Dutta Roy, S. Aneesh, Sayan Kar
We revisit a family of ultra-static Lorentzian wormholes which includes Ellis-Bronnikov spacetime as a special case. We first show how the required total matter stress energy (whic…
