Direction-dependent Jeans instability in an anisotropic Bianchi Type I space-time
May, 2008Citations per year
Abstract: (arXiv)
We derive the metric for a Bianchi Type I space-time with energy density that is dominated by that of a perfect fluid with equation of state p=wρ and whose anisotropy is seeded by a fixed norm spacelike vector field. We solve for the evolution of perturbations about this space-time. In particular, we show that the Jeans instability in an expanding flat Friedmann-Robertson-Walker universe is modified by the presence of the vector field so that energy density perturbations develop direction-dependent growth.References(43)
