REACH: Radio Experiment for the Analysis of Cosmic Hydrogen

The Radio Experiment for the Analysis of Cosmic Hydrogen (REACH) is a new instrument dedicated to the detection of the red-shifted radio signature signal from Hydrogen from the times when the universe transitioned from a vast empty space to a realm of celestial objects. These times are known as the Cosmic Dawn and the Epoch of Re-ionization. REACH will use our best knowledge of the Physics that governed the Universe during these early epochs and of the much brighter foreground signals later added to the faint radio cosmic signal. Furthermore, it will make use of physics rooted models describing the electromagnetic response of the telescope itself, alongside with state of the art Bayesian analysis aiming at opening a new window to the early Universe.
