The BEHOMO project: $\Lambda$LTB $N$-body simulations

Understand

Our Universe may feature large-scale inhomogeneities and anisotropies which cannot be explained by the standard model of cosmology, that is, the homogeneous and isotropic FLRW metric, on which the $\Lambda$CDM model is built, may not describe accurately observations.

• Currently, there is not a satisfactory understanding of the evolution of the large-scale structure on an inhomogeneous background.
• We start the cosmology beyond homogeneity and isotropy (BEHOMO) project and study the inhomogeneous $\Lambda$LTB model with the methods of numerical cosmology.
• Understanding the evolution of the large-scale structure is a necessary step to constrain inhomogeneous models with present and future observables and place the standard model on more solid grounds.
