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

Kavli Affiliate: Radomir Smida | 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 […]

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 […]
