Influence of small-scale inhomogeneities on the cosmological consistency tests
(WILEY-BLACKWELLHOBOKEN, 2012)
The current cosmological dark sector (dark matter plus dark energy) is challenging our comprehension about the physical processes taking place in the Universe. Recently, some authors tried to falsify the basic underlying ...
The baryon mass function for galaxy clusters
(Edp Sciences, 2006-06)
Context.The evolution of the cluster abundance with redshift is known to be a powerful cosmological constraint when applied to X-ray clusters. Recently, the evolution of the baryon mass function has been proposed as a new ...
Is the baryon acoustic oscillation peak a cosmological standard ruler?
(Oxford University Press, 2016)
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 ...
Compatibility of the large quasar groups with the concordance cosmological model
(2016)
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, ...
Scaling of the 1-halo terms with bias
(2015-01-01)
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 ...
Does jackknife scale really matter for accurate large-scale structure covariances?
(Oxford, 2021)
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 ...
Spatial correlations of extended cosmological structures
(Wiley Blackwell Publishing, Inc, 2020-05)
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 ...
