Towards a wave-extraction method for numerical relativity. V. Extracting the Weyl scalars in the quasi-Kinnersley tetrad from spatial data
Lior M. Burko
We extract the Weyl scalars and in the quasi-Kinnersley tetrad by finding initially the (gauge--, tetrad--, and background--independent) transverse quasi-Kinnersley fra…
Orbital evolution for extreme mass-ratio binaries: conservative self forces
Lior M. Burko
The conservative dephasing effects of gravitational self forces for extreme mass-ratio inspirals are studied. Both secular and non-secular conservative effects may have a significa…
Interaction of electromagnetic perturbations with infalling observers inside spherical charged black holes
Lior M. Burko
The electromagnetic radiation that falls into a Reissner-Nordström black hole is known to develop a ``blue sheet'', namely, an infinite concentration of energy density at the Cauch…
Homogeneous spacelike singularities inside spherical black holes
Lior M. Burko
Recent numerical simulations have found that the Cauchy horizon inside spherical charged black holes, when perturbed nonlinearly by a self-gravitating, minimally-coupled, massless,…
Structure of the Cauchy horizon singularity
Lior M. Burko
We study the Cauchy horizon (CH) singularity of a spherical charged black hole perturbed nonlinearly by a self-gravitating massless scalar field. We show numerically that the singu…
Free evolution of nonlinear scalar field collapse in double-null coordinates
Lior M. Burko
We study numerically the fully nonlinear spherically-symmetric collapse of a self-gravitating, minimally-coupled, massless scalar field. Our numerical code is based on double-null…
