The Simons Observatory: Science Goals and Forecasts for the Enhanced Large Aperture Telescope
The Simons Observatory Collaboration, M. Abitbol, I. Abril-Cabezas +419
We describe updated scientific goals for the wide-field, millimeter-wave survey that will be produced by the Simons Observatory (SO). Significant upgrades to the 6-meter SO Large A…
Optical design concept of the CMB-S4 large-aperture telescopes and cameras
Patricio A. Gallardo, Bradford Benson, John Carlstrom +12
CMB-S4 -- the next-generation ground-based cosmic microwave background (CMB) experiment - will significantly advance the sensitivity of CMB measurements and improve our understandi…
The Simons Observatory: Design and Measured Performance of a Carbon Fiber Strut for a Cryogenic Truss
Kevin D. Crowley, Peter Dow, Jordan E. Shroyer +25
We present the design and measured performance of a new carbon fiber strut design that is used in a cryogenically cooled truss for the Simons Observatory Small Aperture Telescope (…
The Simons Observatory: HoloSim-ML: machine learning applied to the efficient analysis of radio holography measurements of complex optical systems
Grace E. Chesmore, Alexandre E. Adler, Nicholas F. Cothard +14
Near-field radio holography is a common method for measuring and aligning mirror surfaces for millimeter and sub-millimeter telescopes. In instruments with more than a single mirro…
The Simons Observatory: the Large Aperture Telescope (LAT)
Zhilei Xu, Shunsuke Adachi, Peter Ade +57
The Simons Observatory (SO) is a Cosmic Microwave Background (CMB) experiment to observe the microwave sky in six frequency bands from 30GHz to 290GHz. The Observatory -- at …
The Simons Observatory Large Aperture Telescope Receiver
Ningfeng Zhu, Tanay Bhandarkar, Gabriele Coppi +68
The Simons Observatory (SO) Large Aperture Telescope Receiver (LATR) will be coupled to the Large Aperture Telescope located at an elevation of 5,200 m on Cerro Toco in Chile. The…
