Validation of harmonic-space likelihood methods for LiteBIRD B-mode polarisation analysis
G. Galloni, P. Campeti, C. Gimeno-Amo +112
The LiteBIRD satellite mission aims to measure the tensor-to-scalar ratio with unprecedented sensitivity through observations of the cosmic microwave background (CMB) -mode…
Using CMB polarization to constrain the anomalous nature of the Cold Spot with an incomplete sky-coverage
R. Fernández-Cobos, P. Vielva, E. Martínez-González +2
Recent results of the ESA Planck satellite have confirmed the existence of some anomalies in the statistical distribution of the cosmic microwave background (CMB) anisotropies. One…
Planck early results. III. First assessment of the Low Frequency Instrument in-flight performance
A. Mennella, M. Bersanelli, R. C. Butler +158
The scientific performance of the Planck Low Frequency Instrument (LFI) after one year of in-orbit operation is presented. We describe the main optical parameters and discuss photo…
Anomalous variance in the WMAP data and Galactic Foreground residuals
M. Cruz, P. Vielva, E. Martínez-González +1
A previous work (Monteserín et al. 2008) estimated the CMB variance from the three-year WMAP data, finding a lower value than expected from Gaussian simulations using the WMAP best…
WMAP anomalous signal in the ecliptic plane
J. M Diego, M. Cruz, J. Gonzalez-Nuevo +3
We report the detection of a high Galactic latitude, large scale, 7-sigma signal in WMAP 5yr and spatially correlated with the ecliptic plane. Two possible candidates are studied,…
The WMAP cold spot
M. Cruz, E. Martinez-Gonzalez, P. Vielva
The WMAP cold spot was found by applying spherical wavelets to the first year WMAP data. An excess of kurtosis of the wavelet coefficient was observed at angular scales of around 5…
