An Improved Measurement of the Secondary Cosmic Microwave Background Anisotropies from the SPT-SZ + SPTpol Surveys

Abstract

We report new measurements of millimeter-wave power spectra in the angular multipole range $2000\le \ell \le 11,000$ (angular scales $5^{\prime }\gtrsim \theta \gtrsim 1^{\prime }$). By adding 95 and 150\,GHz data from the low-noise 500 deg${}^2$ SPTpol survey to the SPT-SZ three-frequency 2540 deg${}^2$ survey, we substantially reduce the uncertainties in these bands. These power spectra include contributions from the primary cosmic microwave background, cosmic infrared background, radio galaxies, and thermal and kinematic Sunyaev-Zel'dovich (SZ) effects. The data favor a thermal SZ (tSZ) power at 143\,GHz of $D_{3000}^{\mathrm{tSZ}}=3.42\pm 0.54\mu {\mathrm{K}}^2$ and a kinematic SZ (kSZ) power of $D_{3000}^{\mathrm{kSZ}}=3.0\pm 1.0\mu {\mathrm{K}}^2$. This is the first measurement of kSZ power at $\ge 3\sigma$. We study the implications of the measured kSZ power for the epoch of reionization, finding the duration of reionization to be $\Delta z_{re}=1.0_{-0.7}^{+1.6}$ ($\Delta z_{re}<4.1$ at 95% confidence), when combined with our previously published tSZ bispectrum measurement.
