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,…

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,…

A multi-frequency study of sub-parsec jets with the Event Horizon Telescope

Jan Röder, Maciek Wielgus, Andrei P. Lobanov +287

The 2017 observing campaign of the Event Horizon Telescope (EHT) delivered the first very long baseline interferometry (VLBI) images at the observing frequency of 230 GHz, leading…

Measurements of the Temperature and E-mode Polarization of the Cosmic Microwave Background from the Full 500-square-degree SPTpol Dataset

T. -L. Chou, P. A. R. Ade, A. J. Anderson +59

Using the full four-year SPTpol 500 deg dataset in both the 95 GHz and 150 GHz frequency bands, we present measurements of the temperature and -mode polarization of the cosm…

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…
