TL;DR: In this paper, the authors presented WMAP seven-year observations of bright sources which are often used as calibrators at microwave frequencies, including the outer planets (Mars, Jupiter, Saturn, Uranus, and Neptune) and five fixed celestial sources (Cas A, Tau A, Cyg A, 3C274, and 3C58).

TL;DR: The Atacama Cosmology Telescope (ACT) in Chile was built to measure the cosmic microwave background (CMB) at arcminute angular scales as discussed by the authors, and a new polarization sensitive receiver for ACT was proposed to characterize the gravitational lensing of the CMB and constrain the sum of the neutrino masses with ~ 0.05 eV precision.

TL;DR: The WMAP satellite has completed 3 years of observations of the cosmic microwave background radiation and the processing used to produce the current sky maps and supporting products represents a significant advancement over the first-year analysis and is described in this paper.

TL;DR: In this paper, the authors study large samples of spectroscopically confirmed type 1 and type 2 AGN lying within the Herschel Multi-tiered Extragalactic Survey (HerMES) fields observed during the science demonstration phase, aiming to understand their FIR colour distributions and constrain their starburst contributions.
