Shear-dependent Pressure in a Lemaître-Tolman-Bondi Metric

preprint2012arXivOpen access

We propose to explain the dimming of distant supernovae as the combined effect of dark energy and a Lemaître-Tolman-Bondi (LTB) metric. We take dark energy to have a shear-dependent pressure $p_{DE}=(w_0+εw_1)ρ_{DE}$ where $ε$ is the ratio of LTB shear to LTB expansion.
