摘要: We present near-IR spectroscopy of 22 luminous low-ionization broad absorption line quasars (LoBAL QSOs) at redshift 1.3 1 there is no clear difference in their optical emission properties. do not see particularly weak [OIII] or strong FeII emission. The LoBAL QSOs show a stronger prevalence ionized gas outflows as traced by the line, compared to normal similar luminosity. conclude that optical-MIR properties are consistent with general quasar population and support them constitute special phase active galactic nucleus evolution.
