The giant nebulae associated with 3C 227: emission-line profiles and kinematic modelling
Detailed line profiles from the nebular gas surrounding the radio galaxy 3C 227 are presented. High-resolution spectroscopy around [O iii] 4959- and 5007-A emission lines, with an unprecedentedly high signal-to-noise ratio, reveals broad and asymmetric line profiles all across the nebulae. The average width of the line complex is of the order of
