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…
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…
First Limits on Light Dark Matter Interactions in a Low Threshold Two Channel Athermal Phonon Detector from the TESSERACT Collaboration
C. L. Chang, Y. -Y. Chang, L. Chaplinsky +45
We present results of a search for spin-independent dark matter-nucleon interactions in a 1 cm by 1 mm thick (0.233 gram) high-resolution silicon athermal phonon detector opera…
First Demonstration of the HeRALD Superfluid Helium Detector Concept
R. Anthony-Petersen, A. Biekert, C. L. Chang +33
The SPICE/HeRALD collaboration is performing R&D to enable studies of sub-GeV dark matter models using a variety of target materials. Here we report our recent progress on instrume…
