Description
As part of this proposal the PI will study theoretical questions connected to the design choices for a mission to probe inflation using the b modes of the CMB polarization. One of the main contaminants for such studies are b modes generated by gravitational lensing. These b modes are expected to dominate on small angular scales but depending on the strength of the gravitational wave background, can also degrade measurements on large angular scales. The lensing contamination can be cleaned if precise measurements of the temperature and polarization on small angular scales are available. Together with a graduate student we will study whether IT is feasible to use ground based measurements of the anisotropies (such as those that will become available with SPT and act) to clean the lensing signal from the b modes measured using lower resolution but higher sensitivity maps produced by a satellite mission. Could such a strategy allow one to improve the sensitivity to intlationary b modes while still having a mission with relatively low resolution and thus lower cost? What are the requirements on the ground based observations for this to be possible? What fraction of the sky should be covered from the ground in order for this strategy to be effective? The PI and the student will also study how such mixed strategy might affect other ancillary science goals of a future polarization mission.
