Intrinsic angular momentum for radiating spacetimes which agrees with the Komar integral in the axisymmetric case
arXiv:1404.2475 · doi:10.1103/PhysRevD.89.084009
Abstract
Here, we present a new definition of {intrinsic angular momentum} at future null infinity, based on the charge-integral approach. This definition is suitable for the general case of radiating spacetimes without symmetries, which does not suffer from supertranslations ambiguities. In the case of axial symmetry this new definition agrees with the Komar integral.
