Abstract

We report new measurements of millimeter-wave power spectra in the angular multipole range 2000 ≤ ℓ ≤ 11,000 (angular scales 5′ ≳ θ ≳ 1′). By adding 95 and 150 GHz data from the low-noise 500 deg2 SPTpol survey to the SPT-SZ three-frequency 2540 deg2 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 D3000tSZ = 3.42 ± 0.54 μK2 and a kinematic SZ (kSZ) power of D3000kSZ = 3.0 ± 1.0 μ K2. This is the first measurement of kSZ power at ≥3σ. However, different assumptions about the CIB or SZ models can reduce the significance down to 2.4σ in the worst case. We study the implications of the measured kSZ power for the epoch of reionization under the Calabrese et al. model for the kSZ power spectrum and find the duration of reionization to be Δzre = 1.1-0.7+1.6 (Δ zre < 4.1 at 95% confidence), when combined with our previously published tSZ bispectrum measurement. The upper limit tightens to Δ zre < 3.2 if the assumed homogeneous kSZ power is increased by 25% (∼0.5 μK2) and relaxes to Δ zre < 5.2 if the homogeneous kSZ power is decreased by the same amount.
