Constraints on Cosmological Parameters from the Angular Power Spectrum of a Combined 2500 deg 2 SPT-SZ and Planck Gravitational Lensing Map
We report constraints on cosmological parameters from the angular power spectrum of a cosmic microwave background (CMB) gravitational lensing potential map created using temperature data from 2500 deg 2 of South Pole Telescope (SPT) data supplemented with data from Planck in the same sky region, wit...
