Spectrum of quasar 0103-294 at z=3.11

This chart shows a spectrum of the distant quasar Q0103-294, obtained with FORS1 at VLT UT1. The redshift z = 3.11 was deduced from the measured wavelengths of the indicated lines of multiple ionized elements, including oxygen, nitrogen, sulphur and carbon, and ionized helium. The spectrum was obtained in the long-slit spectroscopy mode of FORS1. The total exposure time was 30 minutes.
