One of the missing pieces in the puzzle of the history of the Universe is the transition from the Dark Ages after the Big Bang, when the Universe was an empty vast volume, to the complex realm of galaxies, starts, etc. that we can observe from Earth today. In this lecture, Dr de Lera Acedo will give an overview of the current efforts (some of them led from Cambridge) to observe and study the very early lights of our cosmos. Low-frequency radio telescopes, aiming at observing the signature signal from Hydrogen in the early Universe, are widely considered the prime tool to unveil the remaining mysteries around the formation and early evolution of the first luminous objects in the sky. Dr de Lera Acedo will talk about the science case named 21-cm radio cosmology and the different current (eg. REACH, HERA) and future (eg. SKA) experiments and observatories dedicated to this mission.
