Noise estimation in CMB time-streams and fast map-making. Application to the BOOMERanG98 data
S. Prunet, P. A. R. Ade, J. J. Bock +35
We describe here an iterative method for jointly estimating the noise power spectrum from a CMB experiment's time-ordered data, together with the maximum-likelihood map. We test th…
From the time-ordered data to the Maximum-Likelihood temperature maps of the Cosmic Microwave Backgorund anisotropy
R. Stompor, A. Balbi, J. Borrill +10
We review selected methods of the Cosmic Microwave Background data analysis appropriate for the analysis of the largest currently available data sets. We focus on techniques of the…
Detection of anisotropy in the Cosmic Microwave Background at horizon and sub-horizon scales with the BOOMERanG experiment
P. de Bernardis, P. A. R. Ade, J. J. Bock +35
BOOMERanG has recently resolved structures on the last scattering surface at redshift 1100 with high signal to noise ratio. We review the technical advances which made this…
CMB Analysis of Boomerang & Maxima & the Cosmic Parameters {Omega_tot,Omega_b h^2,Omega_cdm h^2,Omega_Lambda,n_s}
J. R. Bond, P. Ade, A. Balbi +40
We show how estimates of parameters characterizing inflation-based theories of structure formation localized over the past year when large scale structure (LSS) information from ga…
Evidence for non-Gaussianity in the CMB
J. Magueijo, P. Ferreira, K. Gorski
In a recent Letter we have shown how COBE-DMR maps may be used to disprove Gaussianity at a high confidence level. In this report we digress on a few issues closely related to this…
The impact on cosmology of a primordial scaling field
Pedro G. Ferreira
A scalar field with an exponential potential has the particular property that it is attracted into a solution in which its energy scales as the dominant component (radiation or mat…
