Planck 2015 results: XV. Gravitational lensing
We present the most significant measurement of the cosmic microwave background (CMB) lensing potential to date (at a level of 40<i>σ<i/>), using temperature and polarization data from the <i>Planck <i/>2015 full-mission release. Using a polarization-only estimator, we detect...

| 520 | |a We present the most significant measurement of the cosmic microwave background (CMB) lensing potential to date (at a level of 40<i>σ<i/>), using temperature and polarization data from the <i>Planck <i/>2015 full-mission release. Using a polarization-only estimator, we detect lensing at a significance of 5<i>σ<i/>. We cross-check the accuracy of our measurement using the wide frequency coverage and complementarity of the temperature and polarization measurements. Public products based on this measurement include an estimate of the lensing potential over approximately 70% of the sky, an estimate of the lensing potential power spectrum in bandpowers for the multipole range 40 ≤ <i>L<i/> ≤ 400, and an associated likelihood for cosmological parameter constraints. We find good agreement between our measurement of the lensing potential power spectrum and that found in the ΛCDM model that best fits the <i>Planck <i/>temperature and polarization power spectra. Using the lensing likelihood alone we obtain a percent-level measurement of the parameter combination σ<sub>8<sub/>Ω<sup>0.25<sup/><sub>m<sub/> = 0.591 ± 0.021. We combine our determination of the lensing potential with the <i>E<i/>-mode polarization, also measured by <i>Planck<i/>, to generate an estimate of the lensing <i>B<i/>-mode. We show that this lensing <i>B<i/>-mode estimate is correlated with the <i>B<i/>-modes observed directly by <i>Planck <i/>at the expected level and with a statistical significance of 10<i>σ<i/>, confirming <i>Planck<i/>’s sensitivity to this known sky signal. We also correlate our lensing potential estimate with the large-scale temperature anisotropies, detecting a cross-correlation at the 3<i>σ<i/> level, as expected because of dark energy in the concordance ΛCDM model. | ||
