Perturbations and Fields on Schwarzschild and Related Metrics  

In General > s.a. black holes in modified theories; black hole perturbations; numerical relativity; spherical solutions.
* Types: Perturbations with l = 0 or 1 correspond to charges, those with l = 2 to gravitational waves; The only stationary axial ones have l = 1; In addition to the quasinormal modes, the gravitational spectrum also has a continuum part, i.e., a branch cut in Green's function, on the negative imaginary frequency axis; Even perturbations satisfy the Zerilli equation, odd ones the Regge-Wheeler equation.
