Cosmic microwave background power spectrum estimation with the destriping technique
Extraction of the CMB (Cosmic Microwave Background) angular power spectrum is a challenging task for current and future CMB experiments due to the large data sets involved. Here we describe an implementation of MASTER (Monte carlo Apodised Spherical Transform EstimatoR) described in Hivon et al. (2002) which exploits the destriping technique as a mapmaking method. In this method a noise estimat...
متن کاملThe Cosmic Microwave Background: beyond the Power Spectrum
Much recent work on the cosmic microwave background (CMB) has focussed on the angular power spectrum of temperature anisotropies and particularly on the recovery of cosmological parameters from acoustic peaks in the power spectrum. However, there is more that can conceivably be done with CMB measurements. Here I briefly survey a few such ideas: cross-correlation with other cosmic backgrounds as...
متن کاملWeak lensing of the cosmic microwave background: Power spectrum covariance
We discuss the non-Gaussian contribution to the power spectrum covariance of cosmic microwave background ~CMB! anisotropies resulting through weak gravitational lensing angular deflections and the correlation of deflections with secondary sources of temperature fluctuations generated by the large scale structure, such as the integrated Sachs-Wolfe effect and the Sunyaev-Zel’dovich effect. This ...
متن کاملCosmic Complementarity: Joint Parameter Estimation from Cosmic Microwave Background Experiments and Redshift Surveys
We study the ability of future cosmic microwave background anisotropy experiments and redshift surveys to constrain a 13-dimensional parameterization of the adiabatic cold dark matter model. Each alone is unable to determine all parameters to high accuracy. However, considered together, one data set resolves the difficulties of the other, allowing certain degenerate parameters to be determined ...
متن کاملTHE COSMIC MICROWAVE BACKGROUND CMB map-making and power spectrum estimation
CMB data analysis is in general done through two main steps : map-making of the time data streams and power spectrum extraction from the maps. The latter basically consists in the separation between the variance of the CMB and that of the noise in the map. Noise must therefore be deeply understood so that the estimation of CMB variance (the power spectrum) is unbiased. I present in this article...
