A framework for large-scale relativistic simulations in the characteristic approach
Roberto Gómez, Willians Barreto, Simonetta Frittelli
We present a new computational framework (LEO), that enables us to carry out the very first large-scale, high-resolution computations in the context of the characteristic approach…

Why does gravitational radiation produce vorticity?
L. Herrera, W. Barreto, J. Carot +1
We calculate the vorticity of world--lines of observers at rest in a Bondi--Sachs frame, produced by gravitational radiation, in a general Sachs metric. We claim that such an effec…

Gravitational Instability of a Kink
W. Barreto, R. Gomez, L. Lehner +1
We study the equilibria of a self-gravitating scalar field in the region outside a reflecting barrier. By introducing a potential difference between the barrier and infinity, we cr…
