Avoiding bias in reconstructing the largest observable scales from partial-sky data
Avoiding bias in reconstructing the largest observable scales from partial-sky data
Obscuration due to Galactic emission complicates the extraction of information from cosmological surveys, and requires some combination of the (typically imperfect) modeling and subtraction of foregrounds, or the removal of part of the sky. This particularly affects the extraction of information from the largest observable scales. Maximum-likelihood estimators for reconstructing …
