Large scale density profiles surrounding halos as cosmological probe

Abstract : The understanding of the cosmic acceleration led to the introduction of the cosmological constant behind the standard ΛCDM model. However, there are many hints of the possibility of more complex Dark Energy which could be understand, at first order, as a Dark Fluid with constant equation of state pDE = w × ρDE. It could also results from a modification of the essence of Gravity such as described in modified gravity models.
