On the horizons in a viable vector-tensor theory of gravitation
Roberto Dale, Màrius J. Fullana, Diego Sáez
A certain vector-tensor (VT) theory of gravitation was tested in previous papers. In the background universe, the vector field of the theory has a certain energy density, which is…
Estimating small angular scale CMB anisotropy with high resolution N-body simulations: weak lensing
M. J. Fullana, J. V. Arnau, R. J. Thacker +2
We estimate the impact of weak lensing by strongly nonlinear cosmological structures on the cosmic microwave background. Accurate calculation of large multipoles requires N-…
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…
On the sources of the late integrated Sachs-Wolfe effect
Marius J. Fullana, Diego Saez
In some scenarios, the peculiar gravitational potential of linear and mildly nonlinear structures depends on time and, as a result of this dependence, a late integrated Sachs-Wolfe…
On the microwave background anisotropy produced by big voids in open universes
M. J. Fullana, J. V. Arnau, D. Sáez
The Tolman-Bondi solution of the Einstein equations is used in order to model the time evolution of the void observed in Boötes. The present density contrast of the central region…
