The Monge-Ampère-Kantorovich approach to reconstruction in cosmology
Roya Mohayaee, Andrei Sobolevskii
Motion of a continuous fluid can be decomposed into an "incompressible" rearrangement, which preserves the volume of each infinitesimal fluid element, and a gradient map that trans…
Reconstruction of large-scale peculiar velocity fields
Roya Mohayaee, Brent Tully, Uriel Frisch
A reconstruction method for recovering the initial conditions of the Universe starting from the present galaxy distribution is presented which guarantees uniqueness of solutions. W…
Formation and Cosmic Evolution of Elliptical Galaxies
J. A. de Freitas Pacheco, R. Michard, R. Mohayaee
A review of the present observational and theoretical status of elliptical galaxies is presented with the aim to clarify whether the monolithic or the hierarchical, is a more viabl…
Evolution of Scale-invariant Inhomogeneities in Standard Cosmology
Elcio Abdalla, Roya Mohayaee
It is shown that density fluctuations obey a scaling law in an open Friedmann universe. In a flat universe, the fluctuations are not scale-invariant. We compute the growth rate of…
