Hawking Radiation via Gravitational Anomalies in Non-spherical Topologies
Eleftherios Papantonopoulos, Petros Skamagoulis
We study the method of calculating the Hawking radiation via gravitational anomalies in gravitational backgrounds of constant negative curvature. We apply the method to topological…
Black Holes and Black String-like Solutions in Codimension-2 Braneworlds
Eleftherios Papantonopoulos
We discuss black hole solutions with a Gauss-Bonnet term in the bulk and an induced gravity term on a thin brane of codimension-2. We show that these black holes can be localized o…
Discontinuities in Scalar Perturbations of Topological Black Holes
George Koutsoumbas, Eleftherios Papantonopoulos, George Siopsis
We study the perturbative behaviour of topological black holes. We calculate both analytically and numerically the quasi-normal modes of scalar perturbations. In the case of small…
Black Holes on Thin 3-branes of Codimension-2 and their Extension into the Bulk
Bertha Cuadros-Melgar, Eleftherios Papantonopoulos, Minas Tsoukalas +1
We discuss black hole solutions in six-dimensional gravity with a Gauss-Bonnet term in the bulk and an induced gravity term on a thin 3-brane of codimension-2. We show that these b…
