Electromagnetic quasinormal modes of D-dimensional black holes II
A. López-Ortega
By using the sixth order WKB approximation we calculate for an electromagnetic field propagating in D-dimensional Schwarzschild and Schwarzschild de Sitter black holes its quasinor…

Dirac quasinormal modes of D-dimensional de Sitter spacetime
A. Lopez-Ortega
We find exact solutions to the Dirac equation in D-dimensional de Sitter spacetime. Using these solutions we analytically calculate the de Sitter quasinormal (QN) frequencies of th…

Strong gravitational lensing from compact bodies: analytical results
Paolo Amore, Mayra Cervantes, Arturo De Pace +1
We develop a non--perturbative method that yields analytical expressions for the deflection angle of light in a general static and spherically symmetric metric. It is an improvemen…
