Dark Ages and ReionizationnChen Xuelei, National Astronomical Observatory, Chinese Academy of SciencesnnThe beginning of our Universe was a highly luminous one: during the Big Bang matter was immersed in a sea of radiation, which is still observable today as the cosmic microwave background (CMB), and the gas were ionized to a plasma state by these high energy photons. As the Universe expands, the wavelength of the photons was stretched (redshifted) to the infrared band, and the plasma recombines
