« Illuminating non-linear structure formation with density-dependent clustering » |
Mark Neyrinck |
The 2-point correlation function and power spectrum optimally quantify a
Gaussian field, but lose information for a non-Gaussian field. I will discuss the "sliced" correlation function, measuring correlations conditional on the density. It is sensitive to different behavior in different density regimes, and also illustrates why a Gaussianizing transform helps to package more information into the usual correlation function. |
