The large-scale structure of the universe

open access: yes, 2016
In this thesis, several theoretical concepts relating to the large-scale structure of the universe are presented. In particular, various aspects of the hierarchical scenario are investigated. The initial perturbation field and its early evolution are discussed in Chapter 3.

Luminosity Distance Dispersion in Swiss-cheese Cosmology as a Function of the Hole Size Distribution

open access: yesThe Astrophysical Journal
The luminosity distance–redshift ( D _L – z ) relation derived from Type Ia supernovae (SNe Ia) yields evidence for a nonzero cosmological constant.

Research in extragalactic astrophysics [PDF]

open access: yes
The spatial distribution of clusters of galaxies and the large scale structure of the universe is investigated. Correlations in the spatial cluster distribution are much stronger than those seen for galaxies, and over scales much larger than previously ...

Constraining Neutrino Cosmologies with Nonlinear Reconstruction

open access: yesThe Astrophysical Journal
Nonlinear gravitational evolution induces strong nonlinearities in the observed cosmological density fields, leading to positive off-diagonal correlations in the power spectrum covariance. This has caused the information saturation in the power spectrum,

Percolation Statistics in the MillenniumTNG Simulations

open access: yesThe Astrophysical Journal
The statistical analysis of cosmic large-scale structure is most often based on simple two-point summary statistics, like the power spectrum or the two-point correlation function of a sample of galaxies or other types of tracers. In contrast, topological
