On the role of shear in cosmological averaging II: large voids, non-empty voids and a network of different voids
Maria Mattsson, Teppo Mattsson
We study the effect of shear on the cosmological backreaction in the context of matching voids and walls together using the exact inhomogeneous Lemaitre-Tolman-Bondi solution. Gene…

On the role of shear in cosmological averaging
Maria Mattsson, Teppo Mattsson
Using the spherically symmetric inhomogeneous Lemaitre-Tolman-Bondi dust solution, we study how the shear and the backreaction depend on the sharpness of the spatial transition bet…

Supernovae data and perturbative deviation from homogeneity
Kari Enqvist, Maria Mattsson, Gerasimos Rigopoulos
We show that a spherically symmetric perturbation of a dust dominated FRW universe in the Newtonian gauge can lead to an apparent acceleration of standard candles and provide…
