Making waves on CMB power spectrum and inflaton dynamics
We discuss cosmic microwave background anisotropies in models with an unconventional primordial power spectrum. In particular, we consider an initial power spectrum with some “spiky” corrections. Interestingly, such a primordial power spectrum generates “wavy” structure in the CMB angular power spectrum. Some possible models generating such a primordial power spectrum from inflaton dynamics are...
متن کاملAngular-planar CMB power spectrum
Gaussianity and statistical isotropy of the universe are modern cosmology's minimal set of hypotheses. In this work we introduce a new statistical test to detect observational deviations from this minimal set. By de ning the temperature correlation function over the whole celestial sphere, we are able to independently quantify both angular and planar dependence (modulations) of the CMB temperat...
متن کاملCmb Anisotropy Power Spectrum Statistics
Much attention has been given to the problem of estimating cosmological parameters from the Cl measured by future experiments. Many of the approaches which are being used either invoke poorly controlled approximations or are computationally expensive. We derive exact results as well as fast and highly accurate approximations for mapping a theoretical model onto the observed power spectrum coeff...
متن کاملCMB Power Spectrum from Noncommutative Spacetime
Very recent CMB data of WMAP offers an opportunity to test inflation models, in particular, the running of spectral index is quite new and can be used to rule out some models. We show that an noncommutative spacetime inflation model gives a good explanation of these new results. In fitting the data, we also obtain a relationship between the noncommutative parameter (string scale) and the ending...
متن کاملCMB Broad-Band Power Spectrum Estimation
The natural outcome of theoretical calculations of microwave background anisotropy is the angular power spectrum Cl as a function of multipole number l. Experimental Cl’s are needed for direct comparison. Estimation procedures using statistics linear in the pixel amplitudes as well as the conventional but less useful quadratic combinations are described. For most current experiments, a single b...
