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,…

OLÉ -- Online Learning Emulation in Cosmology

Sven Günther, Lennart Balkenhol, Christian Fidler +4

In this work, we present OLÉ, a new online learning emulator for use in cosmological inference. The emulator relies on Gaussian Processes and Principal Component Analysis for effic…

The End of Easy Phenomenology for CMB Experiments: A Case Study in the Dark Sector

Cynthia Trendafilova, Ali Rida Khalife, Silvia Galli

The precision of Cosmic Microwave Background (CMB) experiments, specifically its lensing reconstruction, has reached the limit where non-linear corrections cannot be ignored. Negle…
