Interpretation of the extragalactic radio background
M. D. Seiffert,D. J. Fixsen,Alan J. Kogut,S. Levin,Michele Limon,P. Lubin,Paul Mirel,Jack Singal,T. Villela,Edward J. Wollack,Carlos Alexandre Wuensche +10 more
TL;DR: In this article, the authors used absolute calibrated data between 3 and 90 GHz from the 2006 balloon flight of the ARCADE 2 instrument, along with previous measurements at other frequencies, to constrain models of extragalactic emission.

TL;DR: The early dark energy (EDE) scenario aims to increase the value of the Hubble constant (H_0) inferred from cosmic microwave background (CMB) data over that found in $\Lambda$CDM, via the introduction of a new form of energy density in the early universe.
Symmetric Waveguide Orthomode Junctions
Edward J. Wollack,W. Grammer +1 more
TL;DR: In this article, a four-fold symmetric orthomode transducer (OMT) is proposed for millimeter and sub-millimeter imaging applications. But the authors focus on the use of a waveguide orthomod transceiver to increase spectral coverage and sensitivity while reducing exit aperture size and optical spill.

TL;DR: In this article, the authors present an overview of the motivation and design of Prime-Cam, a first-light instrument for CCAT-prime, a 6-meter aperture telescope operating from sub-mm to mm wavelengths, located at 5600 meters elevation on Cerro Chajnantor in Chile.
