Intergalactic Hydrogen and Spectrum of Quasars and Galaxies

Authors: Valery Zhukov

Author present the calculation of the absorption cross section by Lyman alpha line depending on the concentration of neutral hydrogen in intergalactic medium (IGM), different from the calculation, proposed by J. Gunn and B.Peterson. The method proposed by Y. B. Zel'dovich and Y. P. Rajzer serves as a basis for calculation. The calculation shows that the concentration of neutral hydrogen in the IGM can reach 10⁻³ cm³ and more, in this case the Gunn-Peterson effect will not be observed. The probable mechanism of "blueing" of the galaxies spectrum is examined.
