Abstract
We present results of N-body simulations, including effects of cooling and heating due to the background ionizing flux, aimed at modelling space distribution of the Lyα absorbers in the context of cosmological structure formation. The observed z-dependence of the number of Lyα lines per unit redshift is reproduced by the model within the uncertainties. The sharp decrease with time in the number density at high redshift is mainly due to the formation of structures whereas Lyα gas survives at low redshift because of the decreasing ionizing flux.
