Conformally flat polytropes for anisotropic matter
L. Herrera, A. Di Prisco, W. Barreto +1
We analyze in detail conformally flat spherically symmetric fluid distributions, satisfying a polytropic equation of state. Among the two possible families of relativistic polytrop…

Extended two-dimensional characteristic framework to study nonrotating black holes
W. Barreto
We develop a numerical solver, that extends the computational framework considered in [Phys. Rev. D 65, 084016 (2002)], to include scalar perturbations of nonrotating black holes.…

Global energy conservation in nonlinear spherical characteristic evolutions
W. Barreto
Associated to the unique 4-parametric subgroup of translations, normal to the Bondi-Metzner-Sachs group, there exists a generator of the temporal translation asymptotic symmetry. S…
