Description
We investigate whether quasinormal modes can be used in the search for signatures of extra dimensions. To address a gap in the literature, we focus on negative Ricci curvature extra dimensional spacetimes. Starting with a product space comprised of a four-dimensional Schwarzschild space-time and a 3-dimensional nilmanifold, we study the scalar perturbations. The geometry can be characterised as the effective potential of a squared mass-like term. We then compute the corresponding quasinormal frequency spectrum and determine constraints on this possible extra-dimensional observable from gravitational-wave considerations.
