Cosmological parameters from CMB and other data: A Monte Carlo approach

  title={Cosmological parameters from CMB and other data: A Monte Carlo approach},
  author={Antony Lewis and Sarah Bridle},
  journal={Physical Review D},
We present a fast Markov chain Monte Carlo exploration of cosmological parameter space. We perform a joint analysis of results from recent cosmic microwave background ~CMB! experiments and provide parameter constraints, including s 8, from the CMB independent of other data. We next combine data from the CMB, HST Key Project, 2dF galaxy redshift survey, supernovae type Ia and big-bang nucleosynthesis. The Monte Carlo method allows the rapid investigation of a large number of parameters, and we…

Probing cosmological parameters with the CMB: forecasts from Monte Carlo simulations

The Fisher matrix formalism has in recent times become the standard method for predicting the precision with which various cosmological parameters can be extracted from future data. This approach is

Cosmological parameter estimation from CMB and X-ray cluster after Planck

We investigate constraints on cosmological parameters in three 8-parameter models with the summed neutrino mass as a free parameter, by a joint analysis of CCCP X-ray cluster data, the newly released

Cosmological parameter estimation with the Planck satellite data : from the construction of a likelihood to neutrino properties

The cosmic microwave background (CMB), relic of the hot Big-Bang, carries the traces of both the rich structure formation of the late time epochs and the energetic early phases of the universe.The

Estimating the impact of recombination uncertainties on the cosmological parameter constraints from cosmic microwave background experiments

We use our most recent training set for the Rico code to estimate the impact of recom- bination uncertainties on the posterior probability distributions which will be obtained from future CMB

Constraints on cosmological models from Hubble parameters measurements

In this paper, we study the cosmological constraints from the measurements of Hubble parameters - H(z) data. Here, we consider two kinds of H(z) data: the direct H-0 probe from the Hubble Space

Conservative constraints on early cosmology with MONTE PYTHON

Models for the latest stages of the cosmological evolution rely on a less solid theoretical and observational ground than the description of earlier stages like BBN and recombination. As suggested in

Joint cosmological parameters forecast from CFHTLS-cosmic shear and CMB data

We present a prospective analysis of a combined cosmic shear and cosmic microwave background data sets, focusing on a Canada France Hawaii Telescope Legacy Survey (CFHTLS) type lensing survey and the

New constraints on parametrised modified gravity from correlations of the CMB with large scale structure

We study the effects of modified theories of gravity on the cosmic microwave background (CMB) anisotropies power spectrum, and in particular on its large scales, where the integrated Sachs-Wolfe

This is the first of a series of papers in which we derive simultaneous constraints on cosmological parameters and X-ray scaling relations using observations of the growth of massive, X-ray



Is cosmology consistent

We perform a detailed analysis of the latest CMB measurements (including BOOMERaNG, DASI, Maxima and CBI), both alone and jointly with other cosmological data sets involving, e.g., galaxy clustering

The Age of the Universe and the Cosmological Constant Determined from Cosmic Microwave Background Anisotropy Measurements

If Ωtot = 1 and structure formed from adiabatic initial conditions, then the age of the universe, as constrained by measurements of the cosmic microwave background (CMB), is t0 = 14.0 ± 0.5 Gyr. The

Radical Compression of Cosmic Microwave Background Data

A method for approximating the likelihood that takes power spectrum constraints, e.g., "band-powers," as inputs, is presented, and a bias which results if one approximates the probability distribution of the band-power errors as Gaussian is identified.

Bayesian ‘hyper-parameters’ approach to joint estimation: the Hubble constant from CMB measurements

This work generalizes the procedure to allow freedom in the relative weights of various probes by including in the joint χ2 function a set of ‘hyper-parameters’, which are dealt with using Bayesian considerations.

Current constraints on the dark energy equation of state

A method is presented for performing joint analyses of cosmological data sets, in which the weight assigned to each data set is determined directly by its own statistical properties. The weights are
