Dark matter and the formation of large-scale structure in the Universe

A new scenario of clustering in a two component dark matter universe is discussed, from which we would expect the difference between the distributions of quasars and galaxies on the scale of 10–100 Mpc and the difference between the distributions of quasars withZ>2 andZ<2. Several analyses on quasars distribution are in good agreement with these predictions.Paper presented at the IAU Third Asian-Pacific Regional Meeting, held in Kyoto, Japan, between 30 September–6 October, 1984.
