Title: Cosmic Reionization On Computers. Properties of the Post-reionization IGM

We present a comparison between several observational tests of the post-reionization IGM and the numerical simulations of reionization completed under the Cosmic Reionization On Computers (CROC) project. We show that CROC simulations reproduce "out-of-the-box" the observed distributions of Gunn-Peterson optical depths, underscoring the importance of self-consistent modeling of radiative transfer. We also show that CROC simulations match well the observed distributions of dark gaps from SDSS quasars. Finally, we introduce a novel statistical probe of the small-scale structure in the IGM: heights and widths of transmission peaks. Simulations match the peak height distributions reasonably well, but do not reproduce the observed abundance of wide peaks.
