It is therefore relevant for current and next-generation CMBĮxperiments, in the quest for the elusive primordial B-mode signal.With Dual Text you can have two numbers on your iPhone or one number on two different devices like an iPad and your iPhone. This algorithm presents a pathway to exact global analyses of high-resolutionĪnd high-sensitivity CMB data for a statistically optimal separation of E and B Yield unbiased constrained signal realizations, consistent with observed data. To generate fluctuation maps, which, combined with the Wiener filter solution, We show how the algorithm can be modified Implementation of the dual messenger method is straightforward and guarantees In contrast, the PCG implementation fails toĬonverge to a reasonable solution for the specific problem considered. Various convergence diagnostics illustrate the high quality of
With inhomogeneous noise distributions and arbitrary mask geometries with Technique can deal with high-resolution joint temperature and polarization maps Preconditioned conjugate gradient (PCG) solvers, our preconditioner-free Reconstruction and showcase its efficiency and effectiveness in Wienerįiltering polarized cosmic microwave background (CMB) maps.
