<jats:title>Abstract</jats:title>
<jats:p>We analyse the temperature–polarization cross-correlation in the Galactic synchrotron template that we have recently developed, and between the template and cosmic microwave background (CMB) temperature maps derived from WMAP data. Since the polarized synchrotron template itself uses WMAP data, we can estimate residual synchrotron contamination in the CMB CTEℓ angular spectrum. While CTE2 appears to be contaminated by synchrotron, no evidence for contamination is found in the multipole range which is most relevant for the fit of the cosmological optical depth.</jats:p> |
