Improved Measurements of the Temperature and E-Mode Polarization of the CMB from 500 Square Degrees of Multi-Band SPTpol Data

We present the final analysis of the E-mode polarization angular auto-power spectrum (EE) and temperature-E-mode cross-power spectrum (TE) of the cosmic microwave background (CMB) from all four seasons of 500 deg² SPTpol observations, using both frequency bands available (150 GHz and 90 GHz). These measurements are the most sensitive to date of the EE and TE power spectra at multipole ℓ > ∼2000. We also present the best-fit cosmological parameter constraints.
