Scientific paper

A radio map of the high-redshift quasar 4C 04.81 from MERLIN at λ6 cm and a two-component model derived from λ21 cm European VLBI Network observations are presented. The MERLIN map shows a curved jet leading from the radio core to a bright compact hotspot. Despite the high angular resolution of these observations (<0.1 arcsec), most of the source flux at both frequencies originates in unresolved features. Significantly, it is found that the core component has a steep radio spectrum α ≈ -0.8. It is difficult to account for these properties within the framework of current 'unified schemes' of radio sources, which seek to explain differences between normal double sources and core-dominated sources in terms of differing orientation to the line-of-sight.
