Chromaticity-optimized Antenna Design and Bayesian Foreground Validation for the CANTAR Global 21 cm Experiment

Detecting the global 21 cm signal from the epoch of reionization remains a major observational challenge due to bright foregrounds and instrumental systematics. As part of the Colombian Antarctic Telescopes for 21 cm Absorption during Reionization (CANTAR) initiative, we present a simulation and ana...
