Skipper-CCD Sensors for the Oscura Experiment: Requirements and Preliminary Tests

Kavli Affiliate: Paolo Privitera | First 5 Authors: Brenda A. Cervantes-Vergara, Santiago Perez, Juan Estrada, Ana Botti, Claudio R. Chavez | Summary: Oscura is a proposed multi-kg skipper-CCD experiment designed for a dark matter (DM) direct detection search that will reach unprecedented sensitivity to sub-GeV DM-electron interactions with its 10 kg detector array. Oscura is […]

Experimental Evidence of Amplitude-Dependent Surface Wave Dispersion via Nonlinear Contact Resonances

Kavli Affiliate: Chiara Daraio | First 5 Authors: Setare Hajarolasvadi, Paolo Celli, Brian L. Kim, Ahmed E. Elbanna, Chiara Daraio | Summary: In this letter, we provide an experimental demonstration of amplitude-dependent dispersion tuning of surface acoustic waves interacting with nonlinear resonators. Leveraging the similarity between the dispersion properties of plate edge waves and surface […]

Fabrication of a Monolithic 5-Meter Aluminum Reflector for Millimeter-Wavelength Observations of the Cosmic Microwave Background

Kavli Affiliate: Bradford Benson | First 5 Authors: Tyler Natoli, Bradford Benson, John Carlstrom, Eric Chauvin, Bruno Clavel | Summary: We have demonstrated the fabrication of a monolithic, 5-meter diameter, aluminum reflector with 17.4 $mu$m RMS surface error. The reflector was designed to avoid the problem of pickup due to scattering from panel gaps in […]

200,000 Candidate Very Metal-poor Stars in Gaia DR3 XP Spectra

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yupeng Yao, Alexander P. Ji, Sergey E. Koposov, Guilherme Limberg, | Summary: Very metal-poor stars ($rm[Fe/H] < -2$) in the Milky Way are fossil records of early chemical evolution and the assembly and structure of the Galaxy. However, they are rare and hard to find. Gaia […]

Wearing Masks Implies Refuting Trump?: Towards Target-specific User Stance Prediction across Events in COVID-19 and US Election 2020

Kavli Affiliate: Wei Gao | First 5 Authors: Hong Zhang, Haewoon Kwak, Wei Gao, Jisun An, | Summary: People who share similar opinions towards controversial topics could form an echo chamber and may share similar political views toward other topics as well. The existence of such connections, which we call connected behavior, gives researchers a […]
