ELUCID. VI: Cosmic variance of galaxy distribution in the local Universe.
TL;DR: In this paper, a method based on the conditional stellar mass functions in dark matter halos, which can provide an unbiased estimate of the global GSMF has been proposed to deal with the effects of the cosmic variance in the estimate of galaxy stellar mass function.

Genus statistics using the Delaunay tessellation field estimation method: (I) tests with the Millennium Simulation and the SDSS DR7
TL;DR: In this paper, a Delaunay tessellation field estimation (DTFE) technique is used to construct a piece-wise continuous density field and the exact computation of the topology of its polygonal isodensity contours.
