Points are computed at the same set of central $\ell$ values but are horizontally offset for clarity. The lensed values are slightly larger than unlensed values and hence closer to \textit{Planck} values.)

While the power spectra are changed by less than 2\% for all three frequencies, the bispectra and kurtosis change by 10 to 40\% at low $\ell.$ The apparent discrepancy between frequencies for the bispectra and kurtosis arises due to the relatively high flux cut values for \textit{Planck} at lower frequencies.)

As we go to higher-order statistics, the Poisson regime becomes more evident as the spectra flatten out at $\ell > 1000$. We note that the Websky bispectra are mostly within \textit{Planck} error bars even though only the power spectra were fit to match those of \textit{Planck's}. While we do not plot the error...)

• 19:49, 14 August 2024 Njcarlson talk contribs created page File:Deck of cards v5.png (A patch of unlensed CIB and its corresponding lensing convergence for each redshift shell $\Delta z = 0.2$. In our simulations, each unlensed CIB shell is lensed by a convergence shell to create lensed CIB shells, which are then summed up to produce the total lensed CIB map. This method mitigates the `self-lensing' effect substantially. Note that the CIB intensity visibly thins out by $z = 3$, while the integrated lensing convergence becomes brighter at higher redshifts.)
