Rational astrophysics builds models which are studied using only usual, laboratory verified physics. Except close to stars and planets, molecular free paths are larger than duration of pulses making thermal electromagnetic radiations, so that Einstein's theory on optical coherence of light-matter interactions (Einstein1917), in particular Super-radiance and Impulsive Stimulated Raman Scattering (ISRS) apply. A shell of excited atomic hydrogen surrounding a Strömgren's sphere is superradiant, transfering all energy received from stars to bright limbs around optical black holes. Around quasars, optical excitation of cold hydrogen atoms increases 2P state population until a Lyman alpha superradiant flare bursts and, by competition of modes, absorbs a Ly-man forest line. Impulsive stimulated Raman scatterings by hyperfine resonances in 2P state transfer energy from light to cold microwaves, redshifting light, except if energy was previously absorbed at alpha frequency , so that gas lines are visibly absorbed. Thus, quasar spectra, optical black holes, and many other observations are simply explained.
