A Fast Method for Power Spectrum and Foreground Analysis for 21 cm Cosmology
Joshua S. Dillon, Adrian Liu, Max Tegmark
We develop and demonstrate an acceleration of the Liu & Tegmark quadratic estimator formalism for inverse variance foreground subtraction and power spectrum estimation in 21 cm tom…

A Method for 21cm Power Spectrum Estimation in the Presence of Foregrounds
Adrian Liu, Max Tegmark
21cm tomography promises to be a powerful tool for estimating cosmological parameters, constraining the epoch of reionization, and probing the so-called dark ages. However, realizi…

An Improved Method for 21cm Foreground Removal
Adrian Liu, Max Tegmark, Judd Bowman +2
21 cm tomography is expected to be difficult in part because of serious foreground contamination. Previous studies have found that line-of-sight approaches are capable of cleaning…
