Redshifts linked to hydrogen alpha absorption and superradiance.

Spectral line shifts explained by Impulsive Stimulated Raman Scatterings.

Energy exchanges between light and hydrogen atoms support thermodynamic consistency.

Abstract

Spectra of quasars result primarily from interactions of natural light with atomic hydrogen. A visible absorption of a sharp and saturated spectral line in a gas requires a low pressure, so a long path without blushing as a cosmological redshift. Burbidge and Karlsson observed that redshifts of quasars result from fundamental redshifts, written 3K and 4K, that cause a shift of absorbed beta and gamma lines of H to alpha gas line. Thus absorbed spectrum is shifted until an absorbed line overlaps with Lyman alpha line of gas: redshift only occurs if an alpha absorption pumps atoms to 2P state. Thus, space is divided into spherical shells centered on the quasar, containing or not 2P atoms. Neglecting collisional de-excitations in absorbing shells, more and more atoms are excited until amplification of a beam having a long path in a shell, thus perpendicular to the observed ray, is large enough for a superradiant flash at alpha frequency. Energy is provided by atoms and observed ray, absorbing a line at local Lyman alpha frequency. Redshifts of quasars spectra are due to parametric interactions composed of Impulsive Stimulated Raman Scatterings (ISRS) : Excited hydrogen atoms catalyze energy exchanges between observed light rays and background cold rays, in agreement with thermodynamics.
