    • 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 Ly𝛼 line density of Ly𝛼 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.

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
