Equation of state and transport processes in self--similar spheres
W. Barreto, C. Peralta, L. Rosales
We study the effect of transport processes (diffusion and free--streaming) on a collapsing spherically symmetric distribution of matter in a self--similar space--time. A very simpl…

The 3-dimensional Einstein-Klein-Gordon system in characteristic numerical relativity
W. Barreto, A. Da Silva, R. Gomez +3
We incorporate a massless scalar field into a 3-dimensional code for the characteristic evolution of the gravitational field. The extended 3-dimensional code for the Einstein--Klei…
