Direct optimal mapping for 21 cm cosmology: A demonstration with the hydrogen epoch of reionization array
Xu, Zhilei; Hewitt, Jacqueline N.; Bull, Philip (American Astronomical Society, 2022)Motivated by the desire for wide-field images with well-defined statistical properties for 21 cm cosmology, we implement an optimal mapping pipeline that computes a maximum likelihood estimator for the sky using the ...
