Effect of Reionization on High-z Stellar Populations
I will discuss the effects of inhomogeneous reionization on the Spectral Energy Distributions (SED) of galaxies at high redshifts. The formation process of the ionizing sources is modulated by large scale density modes. This makes reionization inhomogeneous and introduces a spread to the reionization times of different regions with the same size. These scale-dependent fluctuations modify the shape of the power spectrum of low-mass galaxies at high redshifts in a way that depends on the history of reionization. High-mass galaxies are affected in a more subtle manner; their star formation histories depend on the local minimum mass of star formation. This produces changes in the SEDs of the galaxies.
