In the Halo Model, galaxies are hosted by dark matter haloes, while the haloes themselves are biased tracers of the underlying matter distribution. Measurements of galaxy correlation functions include contributions both ...

Cold Dark matter (ΛCDM) models have been remarkably successful to explain the observed large scale structure of our universe on scales of the order of galaxy clusters (≥ 4 Mpc) and above (therefore in this work we consider ...

The jackknife method gives an internal covariance estimate for large-scale structure surveys and allows model-independent errors on cosmological parameters. Using the SDSS-III BOSS CMASS sample, we study how the jackknife ...

We study the compatibility of large quasar groups with the concordance cosmological model. Large quasar groups are very large spatial associations of quasars in the cosmic web, with sizes of 50-250 h(-1) Mpc. In particular, ...

Studies of large-scale structures in the Universe, such as superstructures or cosmic voids, have been widely used to characterize the properties of the cosmic web through statistical analyses. On the other hand, the two-point ...

In the standard model of cosmology, the Universe is static in comoving coordinates; expansion occurs homogeneously and is represented by a global scale factor. The baryon acoustic oscillation (BAO) peak location is a ...
