Quasar red shifts under the lens

Gribbin, J.
February 1992
New Scientist;2/8/92, Vol. 133 Issue 1807, p23
Explains doubts surrounding recent suggestions that the red shifts of quasars cannot be explained entirely by the expansion of the universe. Study by Arnon Dar of the Israeli Space Research Institute; Dar's calculations support the lensing interpretation within the standard cosmological framework.
