The spectral decomposition of Active Galactic Nuclei with double-peaked Balmer lines from SDSS

摘要

For a sample of 52 double-peaked broad-lines AGNs from the Sloan Digital Sky Survey (SDSS), we do the spectral decomposition to obtain the host spectrum and the nucleis pectrum from their SDSS spectra, as well as the bulge luminosity (bulge), stellar velocitydi spersion A strong correlation is found between the and the gaseous velocity dispersionin narrow line regions. With the relation, we estimate the black hole masses, range from,and the Eddington ratio from about 0.01 . It is consistentwith the result from relation.
