Two-year Cosmology Large Angular Scale Surveyor (CLASS) Observations: 40 GHz Telescope Pointing, Beam Profile, Window Function, and Polarization Performance
Zhilei Xu, Michael K. Brewer, Pedro Fluxá Rojas +33
The Cosmology Large Angular Scale Surveyor (CLASS) is a telescope array that observes the cosmic microwave background (CMB) over 75% of the sky from the Atacama Desert, Chile, at f…
Sub-Kelvin cooling for two kilopixel bolometer arrays in the PIPER receiver
E. R. Switzer, P. A. R. Ade, T. Baildon +30
The Primordial Inflation Polarization Explorer (PIPER) is a balloon-borne telescope mission to search for inflationary gravitational waves from the early universe. PIPER employs tw…
The CLASS 150/220 GHz Polarimeter Array: Design, Assembly, and Characterization
Sumit Dahal, Mandana Amiri, John W. Appel +17
We report on the development of a polarization-sensitive dichroic (150/220 GHz) detector array for the Cosmology Large Angular Scale Surveyor (CLASS) delivered to the telescope sit…
Atacama Cosmology Telescope: Dusty star-forming galaxies and active galactic nuclei in the equatorial survey
Megan B. Gralla, Tobias A. Marriage, Graeme Addison +30
We present a catalog of 510 radio-loud active galactic nuclei (AGN, primarily blazars) and 287 dusty star-forming galaxies (DSFGs) detected by the Atacama Cosmology Telescope at $>…
