Polarized Redundant-Baseline Calibration for 21 cm Cosmology Without Adding Spectral Structure

Joshua S. Dillon, Saul A. Kohn, Aaron R. Parsons +8

21 cm cosmology is a promising new probe of the evolution of visible matter in our universe, especially during the poorly-constrained Cosmic Dawn and Epoch of Reionization. However…
