A Comparison of Cosmological Parameters Determined from CMB Temperature Power Spectra from the South Pole Telescope and the Planck Satellite

Abstract The Planck cosmic microwave background temperature data are best fit with a ΛCDM model that mildly contradicts constraints from other cosmological probes. The South Pole Telescope (SPT) 2540 <?CDATA ${\deg }^{2}$?> SPT-SZ survey offers measurements on sub-degree angular scales (multipoles <?CDATA $650\leqslant {\ell }\leqslant 2500$?> ) with sufficient precision …
