Direct optimal mapping for 21 cm cosmology: A demonstration with the hydrogen epoch of reionization array
(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 ... -
Direction-dependent corrections in polarimetric radio imaging. Iii. A-to-Z solver— Modeling the full jones antenna aperture illumination pattern
(IOP Publishing, 2022)In this third paper of a series describing direction-dependent corrections for polarimetric radio imaging, we present the the A-to-Z solver methodology to model the full Jones antenna aperture illumination pattern (AIP) ...
