Gravitational self-force from radiation-gauge metric perturbations
Adam Pound, Cesar Merlin, Leor Barack
Calculations of the gravitational self-force (GSF) in curved spacetime require as input the metric perturbation in a sufficiently regular gauge. A basic challenge in the program to…
Completion of metric reconstruction for a particle orbiting a Kerr black hole
Cesar Merlin, Amos Ori, Leor Barack +2
Vacuum perturbations of the Kerr metric can be reconstructed from the corresponding perturbation in either of the two Weyl scalars or , using a procedure described by…
Self-force from reconstructed metric perturbations: numerical implementation in Schwarzschild spacetime
Cesar Merlin, Abhay G. Shah
We present a first numerical implementation of a new scheme by Pound et al. that enables the calculation of the gravitational self-force in Kerr spacetime from a reconstructed metr…
Lorentzian surfaces and the curvature of the Schmidt metric
Yafet Sanchez Sanchez, Cesar Merlin, Ricardo Reynoso Fuentes
The b-boundary is a mathematical tool used to attach a topological boundary to incomplete Lorentzian manifolds using a Riemaniann metric called the Schmidt metric on the frame bund…
The gravitational light shift and the Sachs-Wolfe effect
Cesar Merlin, Marcelo Salgado
Using a 3+1 decomposition of spacetime, we derive a new formula to compute the gravitational light shifts as measured by two observers which are normal to the spacelike hypersurfac…
