Adhesive Gravitational Clustering
Thomas Buchert, Alvaro Dominguez
The notion of `adhesion' has been advanced for the phenomenon of stabilization of large-scale structure emerging from gravitational instability of a cold medium. Recently, the phys…
The Cosmic Quartet - Cosmological Parameters of a Smoothed Inhomogeneous Spacetime
Thomas Buchert, Mauro Carfora
We discuss the relation between `bare' cosmological parameters as the true spatial average characteristics that determine the cosmological model, and the parameters interpreted by…
Universality in the distribution of caustics in the expanding Universe
Taihei Yano, Hiroko Koyama, Thomas Buchert +1
We numerically investigate the long--time evolution of density perturbations after the first appearance of caustics in an expanding cosmological model with one--dimensional `single…
Backreaction in Cosmological Models
Christian Sicka, Thomas Buchert, Martin Kerscher
Most cosmological models studied today are based on the assumption of homogeneity and isotropy. Observationally one can find evidence that supports these assumptions on very large…
Characterizing cluster morphology using vector-valued Minkowski functionals
Claus Beisbart, Thomas Buchert
The morphology of galaxy clusters is quantified using Minkowski functionals, especially the vector-valued ones, which contain directional information and are related to curvature c…
A fresh look at the adhesion approximation
Thomas Buchert
I report on a systematic derivation of the phenomenological ``adhesion approximation'' from gravitational instability together with a brief evaluation of the related status of anal…
