Effects of model incompleteness on the drift-scan calibration of radio telescopes

Bharat K. Gehlot, Daniel C. Jacobs, Judd D. Bowman +76

Precision calibration poses challenges to experiments probing the redshifted 21-cm signal of neutral hydrogen from the Cosmic Dawn and Epoch of Reionization (z~30-6). In both inter…
