Mitigating calibration errors from mutual coupling with time-domain filtering of 21 cm cosmological radio observations

ABSTRACT The 21 cm transition from neutral Hydrogen promises to be the best observational probe of the Epoch of Reionization (EoR). This has led to the construction of low-frequency radio interferometric arrays, such as the Hydrogen Epoch of Reionization Array (HERA), aimed at systematically mapping...
