A Mille-feuille Universe
Résumé
Motivated by seeking kinetic origins for seedsof the large-scale structure formation in the universe,we investigate the properties of a generalizedaxisymmetric Bianchi IX type model. Such a model, which is supposed to describe non-interactingradiation of dust-like matter posterior to decoupling,has the advantage ofbehaving asymptotically as a closefrw model with a cosmological constant. It shows avanishing vorticity, a decreasing shear of matter withtime and a frw chronology, which are properties thatmake it likely when compared to observationalconstraints. The formula which provides us with theredshifts of sources is derived.
