Abstract
Spectra have been obtained of the faint nebulosity north and south of the centre of the QSO 3C48. In addition to the emission lines previously known, a continuum dominated by hot stars is seen at both positions. This suggests that the host galaxy is a spiral and may explain why searches for features indicative of an old stellar population in QSOs have been unsuccessful The redshift of the underlying galaxy is the same as that of the permitted lines in the QSO but differs from the redshift of the forbidden lines in the QSO by 500 km sā1.
