@article{Moreschi2002IntrinsicAM, title={Intrinsic angular momentum and centre of mass in general relativity}, author={Osvaldo M. Moreschi}, journal={Classical and Quantum Gravity}, year={2002}, volume={21}, pages={5409-5425} }
There are several definitions in the literature of the notion of total angular momentum in general relativity. However, none of them can be said to capture the physical notion of intrinsic angular momentum of the sources in the presence of gravitational radiation. We present a definition of angular momentum for radiative spacetimes which does not suffer from any ambiguity of supertranslations. We have succeeded in providing an appropriate notion of intrinsic angular momentum and, at the same…
