Characterization of MKIDs for CMB observation at 220 GHz with the South Pole Telescope

Kavli Affiliate: Clarence L. Chang | First 5 Authors: Karia R. Dibert, Peter S. Barry, Adam J. Anderson, Bradford A. Benson, Thomas Cecil | Summary: We present an updated design of the 220 GHz microwave kinetic inductance detector (MKID) pixel for SPT-3G+, the next-generation camera for the South Pole Telescope. We show results of the […]

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 […]

Angular spectrum of quantum fluctuations in causal structure

Kavli Affiliate: Craig Hogan| First 5 Authors: Craig Hogan, Craig Hogan, , , | Summary:Scaling arguments are used to constrain the angular spectrum of distortions on boundaries of macroscopic causal diamonds, produced by Planck-scale vacuum fluctuations of causally-coherent quantum gravity. The small-angle spectrum of displacement is derived from a form of scale invariance: the variance […]
