Internal delensing of Planck CMB temperature and polarization

Carron, Julien, Lewis, Antony, Challinor, Anthony

Understand

We present a first internal delensing of CMB maps, both in temperature and polarization, using the public foreground-cleaned (SMICA) Planck 2015 maps.

After forming quadratic estimates of the lensing potential, we use the corresponding displacement field to undo the lensing on the same data.
We build differences of the delensed spectra to the original data spectra specifically to look for delensing signatures.
After taking into account reconstruction noise biases in the delensed spectra, we find an expected sharpening of the power spectrum acoustic peaks with a delensing efficiency of $29\,\%$ ($TT$) $25\,\%$ ($TE$) and $22\,\%$ ($EE$).
