摘要：Current attempts to dissect the inner workings of Narrow-Line Seyfert 1 galaxies (NLS1s) rely on the concept that narrow widths of their permitted lines are due to low central black hole masses resulting in high Eddington ratios. Could these narrow lines instead be due to a near pole-on orientation? We analyze spatially resoved spectra of the NLS1 NGC 4051 using the HST STIS G430M grating centered on the bright [O III] emission lines to model the narrow-line region (NLR) outflow and determine its inclination.
