Left. Stacked CMB κ radial profile and image of the Websky mock and WISE-PS1 catalogs using all 2D voids. The κ profiles (with 11 radial bins) show great agreement, with a 7%-higher-than-expected signal at the center, and a clear negative κ value inside of the voids, followed by a clear detection of the void edges in the lensing signal too. We also find good agreement when looking at the stacked images, where a random noise map realization was added to the WebSky mock for a more realistic impression. Right. Here we show the best-fit Aκ parameter values for the fiducial all-voids case (Aκ = 1.05 ± 0.08, i.e., S/N  =  13.1), and we also present our separate northern and southern results. We also show how splitting the void catalogs into two halves at R = 34 h−1 Mpc shows consistent signals. Finally, we also present our main findings when splitting the voids into three redshift bins using a △z ≈ 0.1 width.
