The differences in the narrow-line region of nearby QSOs 1 and 2 – I. Higher excitation and contribution of shocks in type 1s Open
We compare the excitation of the narrow-line region (NLR) of type 1 and type 2 quasi-stellar objects (QSOs) for redshifts $0.4 \le z \le 0.5$ via the analysis of their emission line properties in Sloan Digital Sky Survey near-ultraviolet/o…
