Joint Analysis of CMB Temperature and Polarization Power Spectra
نویسندگان
چکیده
We present a detailed description of analytical methods associated with the joint maximum likelihood estimation of temperature and polarization power spectra from maps produced by Cosmic Microwave Background (CMB) experiments. We investigate the problem both in pixel space and in harmonic domain. The noise properties and issues related to the partial sky coverage are studied. “Electric” and “Magnetic” separation of CMB polarization are analyzed and issues related to pixelisations are investigated. Generalization of maximum-likelihood method using a multi-grid technique is also discussed.

Marginal Distributions for Cosmic Variance Limited Cmb Polarization Data
We provide computationally convenient expressions for all marginal distributions of the polarization CMB power spectrum distribution P (Cl|σl), where Cl = {CTT l , C l , C l , C l } denotes the set of ensemble averaged polarization CMB power spectra, and σl = {σTT l , σ l , σ l , σ l } the set of the realization specific polarization CMB power spectra. This distribution describes the CMB power ...

متن کاملLensed CMB power spectra from all-sky correlation functions
Weak lensing of the CMB changes the unlensed temperature anisotropy and polarization power spectra. Accounting for the lensing effect will be crucial to obtain accurate parameter constraints from sensitive CMB observations. Methods for computing the lensed power spectra using a loworder perturbative expansion are not good enough for percent-level accuracy. Non-perturbative flat-sky methods are ...

We develop the pseudo-Cl method for reconstructing the Cosmic Microwave Background (CMB) temperature and polarization autoand cross-power spectra, and estimate the pseudoCl covariance matrix for a realistic experiment on the cut sky. We calculate the full coupling equations for all six possible CMB power spectra, relating the observed pseudo-Cl’s to the underlying all-sky Cl’s, and test the rec...
متن کاملMulti-frequency Wiener filtering of CMB data with polarization and estimation of cosmological parameters
We present a method of subtracting the foreground contamination for the measurement of CMB polarization. We calculate the resultant errors on CMB polarization and temperature-polarization cross correlation power spectra for the high frequency instrument (HFI) aboard Planck Surveyor, and estimate the corresponding errors on cosmological parameters
