Recent cosmological analyses rely on the ability to accurately sample from high-dimensional posterior distributions. A variety of algorithms have been applied in the field, but justification of the particular sampler choice and settings is often lack

We develop a model for the redshift-space correlation function, valid for both dark matter particles and halos on scales $>5\,h^{-1}$Mpc. In its simplest formulation, the model requires the knowledge of the first three moments of the line-of-sight pa

It is usually assumed that we will need to wait until next-generation surveys like Euclid, LSST and SKA, in order to improve on the current best constraints on primordial non-Gaussianity from the Planck experiment. We show that two contemporary surve

Scaling analysis of dark matter models

Publikováno v: Astroparticle Physics. 5:53-68

We discuss the scaling analysis of CDM and CHDM simulations. We show that on scales larger than about 4–5 h −1 Mpc the two models behave quite differently. In particular, CDM simulations with bias b = 1.5 reveal a smooth transition from small-sca
