A low CMB variance in the WMAP data
C. Monteserin, R. B. Barreiro, P. Vielva +3
We have estimated the CMB variance from the three-year WMAP data, finding a value which is significantly lower than the one expected from Gaussian simulations using the WMAP best-f…
Cosmological applications of a wavelet analysis on the sphere
J. D. McEwen, P. Vielva, Y. Wiaux +6
The cosmic microwave background (CMB) is a relic radiation of the Big Bang and as such it contains a wealth of cosmological information. Statistical analyses of the CMB, in conjunc…
On the excess of power in high resolution CMB experiments
J. M. Diego, P. Vielva, E. Martinez-Gonalez +1
We revisit the possibility that an excess in the CMB power spectrum at small angular scales (CBI, ACBAR) can be due to galaxy clusters (or compact sources in general). We perform a…
Combined MEM and MHW analysis of CMB observations
R. B. Barreiro, P. Vielva, M. P. Hobson +4
We present a combined maximum-entropy method (MEM) and Mexican Hat wavelet (MHW) analysis in order to recover the different components of the microwave sky. We apply this technique…
