Observational constraints on Cosmic Reionization

Abstract

Recent observations have set the first constraints on the epoch of reionization (EoR), corresponding to the formation epoch of the first luminous objects. Studies of Gunn-Peterson (GP) absorption, and related phenomena, suggest a qualitative change in the state of the intergalactic medium (IGM) at $z\sim 6$, indicating a rapid increase in the neutral fraction of the IGM, from $x_{HI}<10^{-4}$ at $z\le 5.5$, to $x_{HI}>10^{-3}$, perhaps up to 0.1, at $z\ge 6$. Conversely, transmission spikes in the GP trough, and the evolution of the \lya galaxy luminosity function indicate $x_{HI}<0.5$ at $z\sim 6.5$, while the large scale polarization of the cosmic microwave background (CMB) implies a significant ionization fraction extending to higher redshifts, $z\sim 11\pm 3$. The results suggest that reionization is less an event than a process, with the process beginning as early as $z\sim 14$, and with the 'percolation', or 'overlap' phase ending at $z\sim 6$. The data are consistent with low luminosity star forming galaxies as being the dominant sources of reionizing photons. Low frequency radio telescopes currently under construction should be able to make the first direct measurements of HI 21cm emission from the neutral IGM during the EoR, and upcoming measurements of secondary CMB temperature anisotropy will provide fine details of the dynamics of the reionized IGM.
