Optical Design of the EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM)
Thomas Essinger-Hileman, Danny Chmaytelli, Trevor Oxholm +23
This work describes the design and implementation of optics for EXCLAIM, the EXperiment for Cryogenic Large-Aperture Intensity Mapping. EXCLAIM is a balloon-borne telescope that wi…
The Simons Observatory: Metamaterial Microwave Absorber (MMA) and its Cryogenic Applications
Zhilei Xu, Grace E. Chesmore, Shunsuke Adachi +26
Controlling stray light at millimeter wavelengths requires special optical design and selection of absorptive materials that should be compatible with cryogenic operating environme…
The Simons Observatory: Modeling Optical Systematics in the Large Aperture Telescope
Jon E. Gudmundsson, Patricio A. Gallardo, Roberto Puddu +35
We present geometrical and physical optics simulation results for the Simons Observatory Large Aperture Telescope. This work was developed as part of the general design process for…
The Atacama Cosmology Telescope: A Catalog of > 4000 Sunyaev-Zel'dovich Galaxy Clusters
M. Hilton, C. Sifón, S. Naess +146
We present a catalog of 4195 optically confirmed Sunyaev-Zel'dovich (SZ) selected galaxy clusters detected with signal-to-noise > 4 in 13,211 deg of sky surveyed by the Atacama…
The Atacama Cosmology Telescope: A Measurement of the Cosmic Microwave Background Power Spectra at 98 and 150 GHz
Steve K. Choi, Matthew Hasselfield, Shuay-Pwu Patty Ho +136
We present the temperature and polarization angular power spectra of the CMB measured by the Atacama Cosmology Telescope (ACT) from 5400 deg of the 2013-2016 survey, which cove…
The Atacama Cosmology Telescope: DR4 Maps and Cosmological Parameters
Simone Aiola, Erminia Calabrese, Loïc Maurin +138
We present new arcminute-resolution maps of the Cosmic Microwave Background temperature and polarization anisotropy from the Atacama Cosmology Telescope, using data taken from 2013…
