The Spectrometer Development of CosmoCube, Lunar Orbiting Satellite to Detect 21-cm Hydrogen Signal from Cosmic Dark Ages
Kaan Artuc, Eloy de Lera Acedo
The cosmic Dark Ages represent a pivotal epoch in the evolution of the Universe, marked by the emergence of the first cosmic structures under the influence of dark matter. The 21-c…

Bayesian data analysis for sky-averaged 21-cm experiments with contamination from linearly polarised foreground
Emma Shen, Dominic Anstey, Marta Spinelli +2
The precise measurement of the sky-averaged HI absorption signal between 50 and 200 MHz is the primary goal of global 21-cm cosmology. This measurement has the potential to unravel…
