Cosmic Microwave Background Polarization and reionization: constraining models with a double reionization
L. P. L. Colombo, G. Bernardi, L. Casarini +4
Neutral hydrogen around high-z QSO and an optical depth tau ~ 0.17 can be reconciled if reionization is more complex than a single transition at z ~ 6-8. Tracing its details could…

A polarized synchrotron template for CMBP experiments after WMAP data
G. Bernardi, E. Carretti, R. Fabbri +4
We build template maps for the polarized Galactic--synchrotron emission on large angular scales (FWHM =~7), in the 20-90 GHz microwave range, by using WMAP data. The method…
