Detection of Millimeter-Wavelength Flares from Two Accreting White Dwarf Systems in the SPT-3G Galactic Plane Survey

Y. Wan, J. D. Vieira, P. M. Chichura +96

Blind discoveries of millimeter-wave (mm-wave) transient events in non-targeted surveys, as opposed to follow-up or pointed observations, have only become possible in the past deca…

Constraints on Inflationary Gravitational Waves with Two Years of SPT-3G Data

J. A. Zebrowski, C. L. Reichardt, A. J. Anderson +95

We present a measurement of the -mode polarization power spectrum of the cosmic microwave background anisotropies at 32 502 for three bands centered at 95, 150,…

Unified and consistent structure growth measurements from joint ACT, SPT and \textit{Planck} CMB lensing

Frank J. Qu, Fei Ge, W. L. Kimmy Wu +143

We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Te…

The SPT-Deep Cluster Catalog: Sunyaev-Zel'dovich Selected Clusters from Combined SPT-3G and SPTpol Measurements over 100 Square Degrees

K. Kornoelje, L. E. Bleem, E. S. Rykoff +191

We present a catalog of 500 galaxy cluster candidates in the SPT-Deep field: a 100 deg field that combines data from the SPT-3G and SPTpol surveys to reach noise levels of 3.0,…

Pointing Accuracy Improvements for the South Pole Telescope with Machine Learning

P. M. Chichura, A. Rahlin, A. J. Anderson +93

We present improvements to the pointing accuracy of the South Pole Telescope (SPT) using machine learning. The ability of the SPT to point accurately at the sky is limited by its s…

Cosmology From CMB Lensing and Delensed EE Power Spectra Using 2019-2020 SPT-3G Polarization Data

F. Ge, M. Millea, E. Camphuis +93

From CMB polarization data alone we reconstruct the CMB lensing power spectrum, comparable in overall constraining power to previous temperature-based reconstructions, and an unlen…
