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…
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…
Deconvolving the Beam in Small Angular Scale CMB Experiments
J. V. Arnau, D. Saez
This paper is concerned with experiments which measure CMB anisotropies on small angular scales. A certain coverage, a beam structure and a level of uncorrelated noise define each…
Learning from observations of the microwave background at small angular scales
D. Sáez, J. V. Arnau
In this paper, we focus our attention on the following question: How well can we recover the power spectrum of the cosmic microwave background from the maps of a given experiment?.…
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…
