Gravitational waves from galaxy encounters
V. Quilis, A. C. González-García, D. Sáez +1
We discuss the emission of gravitational radiation produced in encounters of dark matter galactic halos. To this aim we perform a number of numerical simulations of typical galaxy…
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-circular rotating beams and CMB experiments
J. V. Arnau, A. M. Aliaga, D. Saez
This paper is concerned with small angular scale experiments for the observation of cosmic microwave background anisotropies. In the absence of beam, the effects of partial coverag…
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…
