P. ; Gunn, J. E. ; Turner, E. L. ; Lawrence, C. R. ; Schmidt, M. ; Burke, B. F. Abstract Moderate-resolution slit spectroscopy of the extended emission-line objects A1 and B1 located within 5arcsec of the triple radio source 2016+112 shows that at least one is physically associated with the z = 3.273 quasar thought to be multiply imaged by a foreground galaxy. The data and theoretical models unanimously favor the identification of A1 and B1 with two separate clouds of ionized gas that lie within a few kiloparsecs of the primary A/B QSO and radio source. The available evidence does not support the view that they are multiple images of a single object or their classification as separate (companion) galaxies.
