RADIO STUDIES OF THE DOUBLE QSO, 0957+561A, B

G. G. Pooley; I. W. A. Browne; E. J. Daintree; P. K. Moore; R. G. Noble; Dermot Walsh

The radio source 0957 + 561 has at least four components. Two coincide with the optical QSOs, which is in accordance with the hypothesis that the QSOs are images of a single object due to a gravitational lens. There are details of spectra and structure which are more difficult to reconcile with the hypothesis.
