Query: Non-Gaussian morphology on large scales: Minkowski functionals of the
  REFLEX cluster catalogue   In order to quantify higher-order correlations of the galaxy cluster
distribution we use a complete family of additive measures which give
scale-dependent morphological information. Minkowski functionals can be
expressed analytically in terms of integrals of n-point correlation functions.
They can be compared with measured Minkowski functionals of volume limited
samples extracted from the REFLEX survey. We find significant non-Gaussian
features in the large-scale spatial distribution of galaxy clusters. A
Gauss-Poisson process can be excluded as a viable model for the distribution of
galaxy clusters at the significance level of 95%.
