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…
Scalar quantities as detectors of non-Gaussianity on CMB maps
C. Monteserin, R. B. Barreiro, E. Martinez-Gonzalez +1
We study the power of several scalar quantities constructed on the sphere (presented in Monteserin et al. 2005) to detect non-Gaussianity on the temperature distribution of the cos…
Scalar statistics on the sphere: application to the CMB
C. Monteserin, R. B. Barreiro, J. L. Sanz +1
A method to compute several scalar quantities of Cosmic Microwave Background maps on the sphere is presented. We consider here four type of scalars: the Hessian matrix scalars, the…
