First Constraints on the Epoch of Reionization Using the Non-Gaussianity of the Kinematic Sunyaev-Zel’dovich Effect from the South Pole Telescope and Herschel-SPIRE Observations

S. Raghunathan, Peter A. R. Ade, Adam J. Anderson, B. Ansarinejad et autres

We report results from an analysis aimed at detecting the trispectrum of the kinematic Sunyaev-Zel'dovich (kSZ) effect by combining data from the South Pole Telescope (SPT) and Herschel-SPIRE experiments over a 100 deg^{2} field. The SPT observations combine data from the previous …

Project overview of the Stage-4 Cosmic Microwave Background experiment (CMB-S4)

M. Leitner, J. Aguilar, Zeeshan Ahmed, Kam Arnold et autres

The ground-based Stage-4 Cosmic Microwave Background Experiment (CMB-S4) is a forefront scientific endeavor aimed at mapping the cosmic microwave background (CMB) with unprecedented sensitivity. The cosmic microwave background is the afterglow of the Big Bang and provides crucial insights into the origin …

SPT-SZ MCMF: An extension of the SPT-SZ catalog over the DES region

Matthias Klein, Joseph J. Mohr, S. Bocquet, M. Aguena et autres

We present an extension to a Sunyaev-Zel'dovich Effect (SZE) selected cluster catalog based on observations from the South Pole Telescope (SPT); this catalog extends to lower signal-to-noise than the previous SPT-SZ catalog and therefore includes lower mass clusters. Optically derived redshifts, centers, …

Sidelobe modeling and mitigation for a three mirror anastigmat cosmic microwave background telescope

Ian Gullett, Bradford A. Benson, Robert Besuner, Richard Bihary et autres

Telescopes measuring cosmic microwave background (CMB) polarization on large angular scales require exquisite control of systematic errors to ensure the fidelity of the cosmological results. In particular, far-sidelobe contamination from wide angle scattering is a potentially prominent source of systematic error for …

Review of radio frequency interference and potential impacts on the CMB-S4 cosmic microwave background survey

Darcy R. Barron, A. N. Bender, Ian Birdwell, J. E. Carlstrom et autres

CMB-S4 will map the cosmic microwave background to unprecedented precision, while simultaneously surveying the millimeter-wave time-domain sky, in order to advance our understanding of cosmology and the universe. CMB-S4 will observe from two sites, the South Pole and the Atacama Desert of …

Snowmass 2021 CMB-S4 White Paper

Kevork N. Abazajian, Arwa Abdulghafour, Graeme E. Addison, Peter Adshead et autres

This Snowmass 2021 White Paper describes the Cosmic Microwave Background Stage 4 project CMB-S4, which is designed to cross critical thresholds in our understanding of the origin and evolution of the Universe, from the highest energies at the dawn of time through …

Performance and characterization of the SPT-3G digital frequency-domain multiplexed readout system using an improved noise and crosstalk model

J. Montgomery, Peter A. R. Ade, Zeeshan Ahmed, Ethan Anderes et autres

The third-generation South Pole Telescope camera (SPT-3G) improves upon its predecessor (SPTpol) by an order of magnitude increase in detectors on the focal plane. The technology used to read out and control these detectors, digital frequency-domain multiplexing (DfMUX), is conceptually the same …

Messengers from the Early Universe: Cosmic Neutrinos and Other Light Relics

Daniel Green, Mustafa A. Amin, Joel Meyers, Benjamin Wallisch et autres

The hot dense environment of the early universe is known to have produced large numbers of baryons, photons, and neutrinos. These extreme conditions may have also produced other long-lived species, including new light particles (such as axions or sterile neutrinos) or gravitational …

Year two instrument status of the SPT-3G cosmic microwave background receiver

Faustin W. Carter, T. Cecil, C. L. Chang, Hsaio-Mei Cho et autres

The South Pole Telescope (SPT) is a millimeter-wavelength telescope designed for high-precision measurements of the cosmic microwave background (CMB). The SPT measures both the temperature and polarization of the CMB with a large aperture, resulting in high resolution maps sensitive to signals …
