Systematic QSOs emission line shifts caused by a high-temperature mechanism

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

The observed results exhibit the fact that there are some systematic effects in QSOs spectra, such as: a) the different emission lines give different red-shifts; b) high-ionization lines (HILs) CIV λ1549, NV, CIII] X.1909 and possiblyLy α are systematically blue-shifted to a velocity of about 600 km s−1 with respect to low-ionization lines (LILs) 01, Mgll λ2798 and the balmer lines; c) a systematic red-shift of CIII] to CIV has also been found to correlate in a linear fashion with the red-shift difference between the MgII and CIV. Until now, these effects have not been understood. The motivation of this paper was to present a new mechanism to discuss these effects.
