Properties of the observed Lyα forest.
DEMIANSKI M., DOROSHKEVICH A.G. and TURCHANINOV V.
Abstract (from CDS):
We show that the observed characteristics of the Doppler parameter can be related to the size of DM structure elements that allow us to explain the observed distribution of the Doppler parameter. This distribution is found to be consistent with the Gaussian initial perturbations. The observed characteristics of entropy and column density NHi confirm that the merging of pancakes is the main evolutionary process at redshifts z≥2. The observed sample of absorbers mainly characterizes the matter distribution within large low-density regions and therefore it is difficult to reconstruct the density field from the distribution of absorbers.
