Measurements of Sub-degree B-mode Polarization in the Cosmic Microwave Background from 100 Square Degrees of SPTpol Data

R. Keisler, S. Hoover, N. Harrington +63

We present a measurement of the $B$-mode polarization power spectrum (the $BB$ spectrum) from 100 ${\mathrm{deg}}^2$ of sky observed with SPTpol, a polarization-sensitive receiver cu…
