Bianchi VII_h models and the cold spot texture
M. Bridges, J. D. McEwen, M. Cruz +4
We have returned to our previous Bianchi VII_h analysis in light of the Cruz et al. 2007 suggestion that the cold spot observed near the southern Galactic pole may be a remnant tem…
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…
Non-Gaussianity analysis on local morphological measures of WMAP data
Y. Wiaux, P. Vielva, R. B. Barreiro +2
The decomposition of a signal on the sphere with the steerable wavelet constructed from the second Gaussian derivative gives access to the orientation, signed-intensity, and elonga…
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…
Alignment and signed-intensity anomalies in WMAP data
P. Vielva, Y. Wiaux, E. Martinez-Gonzalez +1
Significant alignment and signed-intensity anomalies of local features of the cosmic microwave background (CMB) are detected on the three-year WMAP data, through a decomposition of…
