The angular momentum of dark halos: merger and accretion effects
Sebastien Peirani, Roya Mohayaee, Jose A. de Freitas Pacheco
We present new results on the angular momentum evolution of dark matter halos. Halos, from N-body simulations, are classified according to their mass growth histories into two cate…
Reconstruction of the early Universe as a convex optimization problem
Y. Brenier, U. Frisch, M. Henon +4
We show that the deterministic past history of the Universe can be uniquely reconstructed from the knowledge of the present mass density field, the latter being inferred from the 3…
Reconstruction of the primordial Universe by a Monge--Ampere--Kantorovich optimisation scheme
R. Mohayaee, U. Frisch, S. Matarrese +1
A method for the reconstruction of the primordial density fluctuation field is presented. Various previous approaches to this problem rendered {\it non-unique} solutions. Here, it…
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…
