Super-sample covariance of the power spectrum, bispectrum, halos, voids, and their cross covariances

The authors study the super-sample covariance (SSC) on higher-order statistics which are becoming standard tools for cosmological inferences from the non-linear small-scale regime of the cosmic structure. To this end, they compare small box sizes of simulations with those embedded in larger simulations that include SCC modes that are cut off by the small boxes. It is observed that these finite-size effects have to be taken into account in future cosmological analyses.
