A fast method for power spectrum and foreground analysis for 21 cm cosmology

A fast method for power spectrum and foreground analysis for 21 cm cosmology

We develop and demonstrate an acceleration of the Liu and Tegmark quadratic estimator formalism for inverse variance foreground subtraction and power spectrum estimation in 21 cm tomography from O(N[superscript 3]) to O(NlogN), where N is the number of voxels of data. This technique makes feasible t...
