Unambiguous angular momentum of radiative spacetimes and asymptotic structure in terms of the center of mass system
Osvaldo M. Moreschi
We present a definition of angular momentum for radiative spacetimes which does not suffer from any ambiguity of supertranslations. We succeed in providing an appropriate notion of…

Characterizing exact solutions from asymptotic physical concepts
Alejandro Perez, Osvaldo M. Moreschi
We contribute to the subject of the physical interpretation of exact solutions by characterizing them through a systematic study in terms of unambiguous physical concepts coming fr…

Cosmic implications on thermodynamics and the explanation of the so called horizon problem
Osvaldo M. Moreschi
We show that there are implications on thermodynamics that come from the existence of the initial cosmic singularity. At present time this is more a conceptual change than an obser…
