Characterization of Transition Edge Sensors for the Simons Observatory
Jason R. Stevens, Nicholas F. Cothard, Eve M. Vavagiakis +31
The Simons Observatory is building both large (6 m) and small (0.5 m) aperture telescopes in the Atacama desert in Chile to observe the cosmic microwave background (CMB) radiation…
The CCAT-Prime Submillimeter Observatory
Manuel Aravena, Jason Austermann, Kaustuv Basu +53
The Cerro Chajnantor Atacama Telescope-prime (CCAT-prime) is a new 6-m, off-axis, low-emissivity, large field-of-view submillimeter telescope scheduled for first light in the last…
Demonstration of 220/280 GHz Multichroic Feedhorn-Coupled TES Polarimeter
Samantha Walker, Carlos E. Sierra, Jason E. Austermann +11
We describe the design and measurement of feedhorn-coupled, transition-edge sensor (TES) polarimeters with two passbands centered at 220 GHz and 280 GHz, intended for observations…
Sensitivity of the Prime-Cam Instrument on the CCAT-prime Telescope
Steve K. Choi, Jason Austermann, Kaustuv Basu +19
CCAT-prime is a new 6 m crossed Dragone telescope designed to characterize the Cosmic Microwave Background (CMB) polarization and foregrounds, measure the Sunyaev-Zel'dovich effect…
The Simons Observatory: Astro2020 Decadal Project Whitepaper
The Simons Observatory Collaboration, Maximilian H. Abitbol, Shunsuke Adachi +280
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) experiment sited on Cerro Toco in the Atacama Desert in Chile that promises to provide breakthrough…
