A Broad-line Quasar with Unexplained Extreme Velocity Offsets: Post-shock Outflow?
The quasar SDSS 0956 + 5128 exhibits three distinct velocity components with large offsets in emission: the systemic velocity of [O ii ], [O iii ], and [Ne iii ] narrow lines have redshift z = 0.7142; the broad Mg ii line is shifted by −1200 km s ^−1 with respect to the narrow lines; the broad H α a...
