The correlation of line strength with luminosity and redshift from composite QSO spectra


We have generated a series of composite QSO spectra using over 22000 individual low resolution (∼ 8Å) QSO spectra obtained from the 2dF (18.25 < bJ < 20.85) and 6dF (16 < bJ ≤ 18.25) QSO Redshift Surveys. The large size of the catalogue has enabled us to construct composite spectra in relatively narrow redshift (∆z = 0.25) and absolute magnitude (∆MB = 0.5… (More)
