An objective classification scheme for QSO spectra
The classification of QSO rest-frame optical and UV spectra is undertaken by means of a statistical principal component analysis (PCA) emphasizing the relation between QSO properties. The PCA is applied directly to a sample of QSO UV spectra from the Large Bright QSO Survey, and relations are studied between continuum, emission-line, and broad-absorption-line properties. Quantitative classifications are derived based on a limited number of principal components, and three components account for...[Show more]
