Scattering of electromagnetic field in quasi-topological gravity
Juan Pablo Arbelaez
We investigate the absorption cross sections of electromagnetic perturbations propagating on a four-dimensional brane in the background of higher-dimensional regular black holes ar…

Grey-body factors of higher dimensional regular black holes in quasi-topological theories
Juan Pablo Arbelaez
We study grey body factors and Hawking radiation of higher dimensional regular black holes arising in quasi topological gravity. These spacetimes incorporate infinite curvature cor…

Quasinormal spectra of higher dimensional regular black holes in theories with infinite curvature corrections
Juan Pablo Arbelaez
We investigate the quasinormal modes of massless scalar and electromagnetic test fields propagating on several families of higher-dimensional regular black holes arising in gravita…
