second, weaker CO source at the QSO itself. At 1.2 mm, the continuum emission is elongated in the direction of the radio jet and towards 3C 48A. We model the 1.2 mm continuum with three different sources in 3C 48 – the 3C 48 QSO, the 3C 48 jet, and the second nucleus 3C 48A. We suggest that the unusually bright and extended nature of the jet may be due to its interaction with the second merger nucleus 3C 48A.
