Simulating Spectral Confusion in SPHEREx Photometry and Redshifts
Zhaoyu Huai, James J. Bock, Yun-Ting Cheng +12
We model the impact of source confusion on photometry and the resulting spectrophotometric redshifts for SPHEREx, a NASA Medium-Class Explorer that is carrying out an all-sky near-…

BICEP/Keck XVIII: Measurement of BICEP3 polarization angles and consequences for constraining cosmic birefringence and inflation
Keck Collaboration, P. A. R. Ade, Z. Ahmed +83
We use a custom-made calibrator to measure individual detectors' polarization angles of BICEP3, a small aperture telescope observing the cosmic microwave background (CMB) at 95GHz…
