The spatial correlation function of nearby Zwicky clusters
Abstract
The two-point three-dimensional correlation function of nearby Zwicky clusters is obtained for a large region of the northern galactic hemisphere (alpha in the range of 9-15 h, delta greater than or equal to zero, and V(0) in the 2000-9000 km/s range). With allowance for galactic absorption and redshift selection, it is found that the correlation function of the Zwicky clusters is similar to the correlation function of galaxies when r is less than 25 Mpc. However, it shows excess clustering when r is in the range of 25-70 Mpc.
