Cluster correlations - A test for biased scenarios
Enrique Martínez-González, J. L. Sanz · The Astrophysical Journal · 1988
The cluster autocorrelation function ξ_c_ and the galaxy-cluster cross-correlation ξ_gc_ are used to test the biased structure formation in several scenarios. A scale-free spectrum can reproduce the observed cluster autocorrelation function ξ_c_, but it is in contradiction to ξ_gc_. On the other hand, acceptable results are obtained for ξ_gc_ in cold dark matter scenarios with adiabatic and isocurvature fluctuations. However, these scenarios are rejected on the grounds of ξ_c_.
