Evolution of Ly α Forest in Redshift Range 0.5 < z < 3.4
Abstract
We collect 23 spectral data from literature, which is regarded as a relatively sufficient sample. The evolution index γ was calculated to study the evolution of Ly α line density of Ly α forest. This paper discusses the relationship between the evolution with the redshift in different interval threshold of column density. The results are in accordance with the results of previous research.
