Bias in Matter Power Spectra ?
M. Douspis, A. Blanchard, J. Silk
We review the constraints given by the linear matter power spectra data on cosmological and bias parameters, comparing the data from the PSCz survey (Hamilton et al., 2000) and fro…
Tests of Gaussianity of CMB maps
E. Martinez-Gonzalez, B. Barreiro, J. M. Diego +5
We study two different methods to test Gaussianity in CMB maps. One of them is based on the partition function and the other on the morphology of hot and cold spots. The partition…
Strong constraints on cosmology from galaxy clusters
J. M. Diego, E. Martinez-Gonzalez, J. L. Sanz +2
In this work we show how galaxy clusters can be used to discriminate among different cosmological models. We have used available X-ray & optical cluster data to constrain the cosmo…
Isotropic Wavelets: a Powerful Tool to Extract Point Sources from CMB Maps
L. Cayon, J. L. Sanz, R. B. Barreiro +6
It is the aim of this paper to introduce the use of isotropic wavelets to detect and determine the flux of point sources appearing in CMB maps. The most suited wavelet to detect po…
Correlation of Excursion Sets for Non-Gaussian CMB Temperature Distributions
R. B. Barreiro, J. L. Sanz, E. Martinez-Gonzalez +1
We present a method, based on the correlation function of excursion sets above a given threshold, to test the Gaussianity of the CMB temperature fluctuations in the sky. In particu…
