Cosmic microwave background (CMB) temperature and polarization anisotropies from Planck have estimated a lower value of the optical depth to reionization (τ ) compared to WMAP. A significant period in the reionization history would then fall within 6 <redshift(z )<10 , where detection of galaxies with Hubble frontier fields program and indep…
