Dipole $\Lambda$CDM model: Towards a realistic model building in dipole cosmology

Dipole cosmology is the maximally Copernican generalization of the FLRW paradigm that can incorporate bulk flows in the cosmic fluid. In this paper, Prof. Shahin Sheik-Jabbari (School of Physics, Institute for Research in Fundamental Sciences, Tehran, Iran) first discuss how multiple fluid components with independent flows can be realized in this set up. This is the necessary step to promote “tilted” Bianchi cosmologies to a viable framework for cosmological model building involving fluid mixtures (as in FLRW).
