Detecting the 21 cm emission from this time, all the way through to the end of reionization, has been proposed as a powerful way of studying early structure formation.
32.
In the period during and after reionization, but before significant expansion had occurred to sufficiently lower the electron density, the light that composes the CMB will experience observable Thomson scattering.
33.
In its early phase ISOLTRAP used a stopping-reionization procedure in which the 60 keV ions, delivered from ISOLDE in a continuous beam, were implanted in a rhenium foil.

For his mapping of the cosmic microwave background and determining the universe's age, mass-energy content, geometry, expansion rate, and reionization epoch with unprecedented precision.

In August 2014, a 3-day workshop was held at the AlbaNova University Center, part of Stockholm University, titled : " Lyman Continuum Leakage and Cosmic Reionization ".
36.
The age of EGS-zs8-1 places it in the reionization phase of creation, a time when hydrogen outside the galaxies was switching from a neutral to ionized state.
37.
The parameter usually quoted here is ?, the " optical depth to recombination, " or alternatively, z re, the redshift of reionization, assuming it was an instantaneous event.
38.
EGS-zs8-1 was born 670 million years after the Big Bang, during the period of reionization, and it's 15 percent the size of the Milky Way.
39.
By looking at the CMB anisotropies observed, and comparing with what they would look like had reionization not taken place, the electron column density at the time of reionization can be determined.
