The Highly Damped Quasinormal Modes of Extremal Reissner-Nordström and Reissner-Nordström-de Sitter Black Holes

Ramin G. Daghigh, Michael Green

We analyze in detail the highly damped quasinormal modes of $D$-dimensional extremal Reissner-Nordstr$\ddot{\mathrm{o}}$m and Reissner-Nordstr$\ddot{\mathrm{o}}$m-de Sitter black holes. We…
