In cosmology, it’s common to use the two point
correlation function, to explore statistics. However in
deeply non-linear regimes of the cosmic web, the
statistics is not Gaussian. As a result, the two-point
correlation function doesn’t probe all the information.
We can make new quantities to reach more information
from non-linear regimes. The Spherical contact and
Nearest neighbor distributions are two example of such
functions. In this talk I’m going to speak about
advantage of these two functions and our new work MA
et.al. (2021) (2106.13216). The most important point for
our talk is that these functions are influenced by higher
order correlation functions. So they can be used as
statistics together with the two point correlation
function.
