GLOBALEMU: A novel and robust approach for emulating the sky-averaged 21-cm signal from the cosmic dawn and epoch of reionisation
H. T. J. Bevins, W. J. Handley, A. Fialkov +2
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…

maxsmooth: Rapid Maximally Smooth Function Fitting With Applications in Global 21-cm Cosmology
H. T. J. Bevins, W. J. Handley, A. Fialkov +3
Maximally Smooth Functions (MSFs) are a form of constrained functions in which there are no inflection points or zero crossings in high order derivatives. Consequently, they have a…

An updated estimate of the cosmic radio background and implications for ultra-high-energy photon propagation
I. C. Niţu, H. T. J. Bevins, J. D. Bray +1
We present an updated estimate of the cosmic radio background (CRB) and the corresponding attenuation lengths for ultra-high energy photons. This new estimate provides associated u…
