TL;DR: In this article, the angular power spectrum of a 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, with the statistical power in the combined map primarily from the SPT data.

TL;DR: The South Pole Telescope (SPT) is a millimeter-wavelength telescope designed for high-precision measurements of the cosmic microwave background (CMB) with a large aperture, resulting in high resolution maps sensitive to signals across a wide range of angular scales on the sky as discussed by the authors.
Proceedings ArticleDOI
Multichroic dual-polarization bolometric detectors for studies of the cosmic microwave background

TL;DR: In this paper, a silicon lens-coupled dual polarized sinuous antenna collects light over a two-octave frequency band, and the antenna couples the broadband millimeter wave signal into microstrip transmission lines, and on-chip filter banks split the broadband signal into several frequency bands.

A Method for Individual Source Brightness Estimation in Single- and Multi-band Data
T. M. Crawford,Eric R. Switzer,W. L. Holzapfel,Christian L. Reichardt,Daniel P. Marrone,Daniel P. Marrone,Joaquin Vieira +6 more
TL;DR: It is found that proper treatment of the correlated prior information between observing bands is key to avoiding significant biases in estimations of multi-band fluxes and spectral behavior, biases which lead to significant numbers of misclassified sources.
