Title: A Measurement of the Cosmic Microwave Background Lensing Potential and Power Spectrum from 500 deg2 of SPTpol Temperature and Polarization Data

Abstract

© 2019. The American Astronomical Society. All rights reserved. We present a measurement of the cosmic microwave background lensing potential using 500 deg2 of 150 GHz data from the SPTpol receiver on the South Pole Telescope. The lensing potential is reconstructed with signal-to-noise per mode greater than unity at lensing multipoles L ≲ 250, using a quadratic estimator on a combination of cosmic microwave background temperature and polarization maps. We report measurements of the lensing potential power spectrum in the multipole range of 100 < L < 2000 from sets of temperature-only (T), polarization-only (POL), and minimum-variance (MV) estimators. We measure the lensing amplitude by taking the ratio of the measured spectrum to the expected spectrum from the best-fit Λ cold dark matter model to the Planck 2015 TT + low P + lensing data set. For the minimum-variance estimator, we find =0.944 0.025 (Sys.) SRC=restricting to only polarization data, we find POL=0.906\pm 0.090 0.040. Considering statistical uncertainties alone, this is the most precise polarization-only lensing amplitude constraint to date (10.1σ) and is more precise than our temperature-only constraint. We perform null tests and consistency checks and find no evidence for significant contamination.

Fig. 1 Fig. 1: Bias terms subtracted from the raw MV lensing spectrum: N$^{(0),RD}_{L}$ , N$^{(1)}_{L}$ (converted to C$^{κκ}_{L}$ units, Eq. (12)), and foreground bias ΔC$^{κκ, FG}_{L}$ . The theoretical lensing convergence spectrum for the fiducial cosmology is shown in black. The disconnected term in the CMB 4-point function N$^{(0),RD}_{L}$ is shownmore » in dashed yellow (Eq. (8)). The spurious correlated power between the CMB and the lensing potential N$^{(1)}_{L}$ is shown in dashed pink (Eq. (9)). The sum of these two terms is labeled \Total Noise Bias" in the figure in solid green. The foreground bias from the tSZ trispectrum, CIB trispectrum, and the tSZ and CIB correlation with κ is shown in dashed dark blue (Section 3.3). The total noise bias is also an estimate of the noise in the reconstructed $\phi$ map. Lensing modes with values of L for which the total bias is less than the signal spectrum are measured at signal-to-noise greater than unity. For this measurement, that includes all modes with L≲ 250, or angular scales of roughly a degree and larger.« less
