Proposal for the origin of the cosmological constant
R. Dale, J. A. Morales-Lladosa, D. Saez
We work in the framework of a simple vector-tensor theory. The parametrized post-Newtonian approximation of this theory is identical to that of general relativity. Our attention is…
On the Rees-Sciama effect: maps and statistics
N. Puchades, M. J. Fullana, J. V. Arnau +1
Small maps of the Rees-Sciama (RS) effect are simulated by using an appropriate N-body code and a certain ray-tracing procedure. A method designed for the statistical analysis of c…
CMB maps lensed by cosmological structures: Simulations and statistical analysis
L. Antón, P. Cerdá-Durán, V. Quilis +1
A method for ray-tracing through n-body simulations has been recently proposed. It is based on a periodic universe covered by simulation boxes. Photons move along appropriate direc…
Beam deconvolution in noisy CMB maps
Carlo Burigana, Diego Saez
The subject of this paper is beam deconvolution in small angular scale CMB experiments. The beam effect is reversed using the Jacobi iterative method, which was designed to solved…
Non--Linear Dynamics of Irrotational Dust: Eulerian and Lagrangian Approaches
S. Matarrese, P. Catelan, F. Lucchin +3
Some recently proposed approximations to follow the non--linear evolution of collisionless matter perturbations in the universe are reviewed. The first one, called frozen--flow app…
