Abstract

We present a cosmic microwave background (CMB) lensing map produced from a linear combination of South Pole Telescope (SPT) and Planck temperature data. The 150 GHz temperature data from the 2500 deg² SPT-SZ survey is combined with the Planck 143 GHz data in harmonic space, to obtain a temperature map that has a broader ` coverage and less noise than either individual map. Using a quadratic estimator technique on this combined temperature map, we produce a map of the gravitational lensing potential projected along the line of sight. We measure the auto-spectrum of the lensing potential C_L^φφ, and compare it to the theoretical prediction for a ΛCDM cosmology consistent with the Planck 2015 data set, finding a best-fit amplitude of 0.95⁺⁰₋₀^._.⁰⁶₀₆(Stat.)⁺⁰₋₀^._.⁰¹₀₁(Sys.). The null hypothesis of no lensing is rejected at a significance of 24 σ. One important use of such a lensing potential map is in cross-correlations with other dark matter tracers. We demonstrate this cross-correlation in practice by calculating the cross-spectrum, C_L^φG, between the SPT+Planck lensing map and Wide-field Infrared Survey Explorer (WISE) galaxies. We fit C_L^φG to a power law of the form pL = a(L/L₀)^−b with a = 2.15 × 10⁻⁸, b = 1.35, L₀ = 490, and find η^φG = 0.94₋⁺⁰₀^._.⁰⁴₀₄, which is marginally lower, but in good agreement with η^φG = 1.00⁺⁰₋₀^._.⁰²₀₁, the best-fit amplitude for the cross-correlation of Planck-2015 CMB lensing and WISE galaxies over ∼ 67% of the sky. The lensing potential map presented here will be used for cross-correlation studies with the Dark Energy Survey (DES), whose footprint nearly completely covers the SPT 2500 deg² field.
