Molecular hydrogen in distant galaxy
Spectrum of the quasar PSS J 1443+2724, revealing the otherwise invisible galaxy at a redshift of 4.224. The velocity profiles of selected transition lines from some rotational levels of H2 are shown. The best fit is superposed in red on the observed spectrum (in black).
