The CMB Cold Spot under the lens II: Lensing signatures in polarization and cosmic texture footprints
Forecasts indicate Simons Observatory could reach 1.5-2.3 sigma sensitivity to sub-10 arcsecond lensing from a cosmic texture using temperature and polarization channels, with polarization boosting signal-to-noise by about 67 percent.
