Colliding black holes from a null point of view: the close limit
Sascha Husa, Manuela Campanelli, Roberto Gomez +2
We present a characteristic algorithm for computing the perturbations of a Schwarzschild spacetime by means of solving the Teukolsky equations. Our methods and results are expected…

Black hole collisions: how far can perturbation theory go?
Manuela Campanelli
The computation of gravitational radiation generated by the coalescence of inspiralling binary black holes is nowdays one of the main goals of numerical relativity. Perturbation th…

Comment on ``Perturbative Method to solve fourth-order Gravity Field Equations"
Manuela Campanelli
We reconsider the cosmic string perturbative solution to the classical fourth-order gravity field equations, obtained in Ref.\cite{CLA94}, and we obtain that static, cylindricaly s…
