LiteBIRD science goals and forecasts: improved full-sky reconstruction of the gravitational lensing potential through the combination of Planck and LiteBIRD data
M. Ruiz-Granda, P. Diego-Palazuelos, C. Gimeno-Amo +102
Cosmic microwave background (CMB) photons are deflected by large-scale structure through gravitational lensing. This secondary effect introduces higher-order correlations in CMB an…
Requirements on bandpass resolution and measurement precision for LiteBIRD
