On computations of angular momentum and its flux in numerical relativity
Emanuel Gallo, Luis Lehner, Osvaldo M. Moreschi
The purpose of this note is to point out ambiguities that appear in the calculation of angular momentum and its radiated counterpart when some simple formulae are used to compute t…

Estimates of the total gravitation radiation in the head-on black hole collision
Osvaldo M. Moreschi, Sergio Dain
We report on calculations of the total gravitational energy radiated in the head-on black hole collision, where we use the geometry of the Robinson-Trautman metrics.

The Goldberg-Sachs theorem in linearized gravity
S. Dain, O. M. Moreschi
The Goldberg-Sachs theorem has been very useful in constructing algebraically special exact solutions of Einstein vacuum equation. Most of the physical meaningful vacuum exact solu…
