Constraints on cosmological parameters from recent measurements of CMB anisotropy
A key prediction of cosmological theories for the origin and evolution of structure in the Universe is the existence of a ‘Doppler peak’ in the angular power spectrum of cosmic microwave background (CMB) fluctuations. We present new results from a study of recent CMB observations which provide the first strong evidence for the existence of a ‘Doppler Peak’ localised in both angular scale and am...
متن کاملConstraints on Cosmological Parameters from Current Cmb Data
We discuss the constraints one can place on cosmological parameters using current cosmic microwave background data. A standard χ– minimization over band–power estimates is first presented, followed by a discussion of the more correct likelihood approach. We propose an approximation to the complete likelihood function of an arbitrary experiment requiring only limited and easily found information...
متن کاملCurrent Cosmological Constraints from a 10 Parameter Cmb Analysis
We compute the constraints on a “standard” 10 parameter cold dark matter (CDM) model from the most recent CMB and data and other observations, exploring 30 million discrete models and two continuous parameters. Our parameters are the densities of CDM, baryons, neutrinos, vacuum energy and curvature, the reionization optical depth, and the normalization and tilt for both scalar and tensor fluctu...
متن کاملCosmological constraints from the CMB and Ly-α forest revisited
The WMAP team has recently highlighted the usefulness of combining the Ly-α forest constraints with those from the cosmic microwave background. This combination is particularly powerful as a probe of the primordial shape of the power spectrum. Converting between the Ly-α forest observations and the linear mass power spectrum requires a careful treatment of nuisance parameters and modeling with ...
متن کاملImproved Cosmological Parameters Constraints from CMB and H(z) Data
We discuss the cosmological degeneracy between the Hubble parameter H(z), the age of the universe and cosmological parameters describing simple variations from the minimal ΛCDM model. We show that independent determinations of the Hubble parameter H(z) such as those recently obtained from ages of passively evolving galaxies, combined with Cosmic Microwave Background data (WMAP 5years), provides...
