摘要: We present recent observations of several near infrared emission lines highly ionized (IP ≱ 100eV) species in NGC1068 which appear to be emitted predominantly within the NE ionization cone; peak at 30pc from nucleus and are blueshifted by ≃ 300 km s-1 relative systemic velocity. The blueshift is same as that observed for better known Fe coronal visible absence red-shifted components less extincted suggests any counter-cone SW intrinsically faint rather than heavily obscured. Following a review possible mechanisms comparison line ratios with models we conclude arises outflowing gas photoionized EUV continuum AGN.
