Test of the gravitational lens hypothesis for the quasar pair 1146+111B,C

P. A. Shaver & S. Cristiani

European Southern Observatory, Karl-Schwarzschild-Str. 2, D-8046 Garching bei München, FRG

It has recently been suggested1 that the quasars 1146 + 111B,C, separated on the sky by 2.6 arc min, are actually two images of a single object produced by an extremely massive gravitational lens. The basis for this suggestion is the similarity in redshifts (within 100–200 km s−1) and spectral features. Here we report differences between the two spectra in a hitherto unobserved range, suggesting that the two images are in fact distinct quasars located close together in space.
