Exploring cosmic rays ionization power

After the so-called cosmic recombination the expanding universe entered into a period of darkness, since most of the matter was in a neutral state. However, about a billion years later the intergalactic space was once again ionized. The process, known as the cosmic reionization, required the operati...
