Large-scale inhomogeneities in modified Chaplygin gas cosmologies

Mostrar todas las versiones(3)

We extend the homogeneous modified Chaplygin cosmologies to large-scale perturbations by formulating a Zeldovich-like approximation. We show that the model interpolates between an epoch with a soft equation of state and a de Sitter phase, and that in the intermediate regime its matter content is sim...
