SPT-3G D1: A Measurement of Secondary Cosmic Microwave Background Anisotropy Power
P. Chaubal, N. Huang, C. L. Reichardt +104
The authors present new measurements of the small‑scale CMB temperature power spectrum from two years of SPT‑3G data, using 95, 150, and 220 GHz observations to constrain thermal a…
Galaxy Clusters Selected via the Sunyaev-Zel'dovich Effect in 5 year data from the SPT-3G Main Survey
L. E. Bleem, M. Klein, K. Kornoelje +148
We report a new galaxy cluster catalog, selected using the thermal Sunyaev-Zel'dovich (SZ) effect, from 5 years of observations of the SPT-3G Main field. Drawn from arcminute-resol…
Inflation at the End of 2025: Constraints on and Using the Latest CMB and BAO Data
L. Balkenhol, E. Camphuis, F. Finelli +10
Inflation elegantly provides initial conditions for the standard model of cosmology, while solving the horizon, flatness, and magnetic monopole problems. Inflationary models make p…
Characterization of the Polarization Beam Response of SPT-3G Using Point Sources
T. de Haan, M. Archipley, N. Huang +101
Precise measurements of cosmic microwave background (CMB) polarization require rigorous control of instrumental systematics. For the South Pole Telescope's third-generation camera…
SPT-3G D1: Axion Early Dark Energy with CMB experiments and DESI
A. R. Khalife, L. Balkenhol, E. Camphuis +92
We present the most up-to-date constraints on axion early dark energy (AEDE) from cosmic microwave background (CMB) and baryon acoustic oscillation (BAO) measurements. In particula…
Measurement of the Full Shape of the Thermal Sunyaev-Zeldovich Power Spectrum from South Pole Telescope and {\it Herschel}-SPIRE Observations
S. Raghunathan, P. A. R. Ade, D. Anbajagane +139
We present a measurement of the full shape of the power spectrum of the thermal Sunyaev-Zeldovich (tSZ) effect down to arcminute scales using cosmic microwave background (CMB) data…
