Joint analysis constraints on the physics of the first galaxies with low-frequency radio astronomy data
Joint analysis constraints on the physics of the first galaxies with low-frequency radio astronomy data
ABSTRACT The first billion years of cosmic history remains largely unobserved. We demonstrate, using a novel machine learning technique, how combining upper limits on the spatial fluctuations in the 21-cm signal with observations of the sky-averaged 21-cm signal from neutral hydrogen can improve our understanding of this epoch. By jointly …
