<scp>globalemu</scp>: a novel and robust approach for emulating the sky-averaged 21-cm signal from the cosmic dawn and epoch of reionization
Emulation of the Global (sky-averaged) 21-cm signal with neural networks has been shown to be an essential tool for physical signal modelling. In this paper we present globalemu, a Global 21-cm signal emulator that uses redshift as a character defining variable alongside a set of astrophysical parameters to estimate the …
