Accurate method for ultralight axion CMB and matter power spectra

Posted by Chicago

Kavli Affiliate: Wayne Hu | First 5 Authors: Rayne Liu, Wayne Hu, Daniel Grin, , | Summary: Ultralight axions (ULAs) with masses $10^{-33} lesssim m/{rm eV} lesssim 10^{-12}$ are well motivated in string-inspired models and can be part or all of the dark energy or the dark matter in this range. Since the ULA field […]

Pointing Accuracy Improvements for the South Pole Telescope with Machine Learning

Posted by Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: P. M. Chichura, A. Rahlin, A. J. Anderson, B. Ansarinejad, M. Archipley | Summary: We present improvements to the pointing accuracy of the South Pole Telescope (SPT) using machine learning. The ability of the SPT to point accurately at the sky is limited by its structural imperfections, […]
