TL;DR: In this paper, the angular power spectra derived from the 7-year maps and discuss the cosmological conclusions that can be inferred from WMAP data alone, including the existence of pre-stellar helium at > 3 sigma.

TL;DR: ACTPol as mentioned in this paper is an upgraded receiver for ACT, which uses feedhorn-coupled, polarization-sensitive detector arrays, a 3° field of view, 100 mK cryogenics with continuous cooling, and meta material antireflection coatings.

First Year Wilkinson Microwave Anisotropy Probe Observations: Dark Energy Induced Correlation with Radio Sources
M. R. Nolta,Edward L. Wright,Lyman A. Page,Charles L. Bennett,Mark Halpern,Gary Hinshaw,Norman Jarosik,A. Kogut,Michele Limon,Michele Limon,S. S. Meyer,David N. Spergel,Gregory S. Tucker,Gregory S. Tucker,Edward J. Wollack +14 more
TL;DR: In this paper, the first-year Wilkinson Microwave Anisotropy Probe (WMAP) data, in combination with any one of a number of other cosmic probes, show that we live in a flat Λ-dominated cold dark matter (CDM) universe with Ωm ≈ 0.28, h = 0.33, and no dark energy component (ΩΛ = 0) would produce an anticorrelation between the matter distribution and the CMB.
