Interpreting deviations between AR-VTG and GR
Roberto Dale, Diego Sáez
The Cosmic microwave background (CMB) anisotropies predicted by two cosmological models are compared, one of them is the standard model of general relativity with cold dark matter…
On the viability of a certain vector-tensor theory of gravitation
R. Dale, D. Saez
A certain vector-tensor theory is revisited. Our attention is focused on cosmology. Against previous suggestions based on preliminary studies, it is shown that, if the energy densi…
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-…
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…
