Lagrangian theory of structure formation in relativistic cosmology. IV. Lagrangian approach to gravitational waves
Fosca Al Roumi, Thomas Buchert, Alexander Wiegand
The relativistic generalization of the Newtonian Lagrangian perturbation theory is investigated. In previous works, the perturbation and solution schemes that are generated by the…
On Backreaction in Newtonian cosmology
Thomas Buchert
We clarify that a result recently stated by Kaiser is contained in a theorem of Buchert and Ehlers that is widely known for its main result: that there is no global kinematical bac…
Order-unity argument for structure-generated "extra" expansion
Boudewijn F. Roukema, Jan J. Ostrowski, Thomas Buchert +1
Self-consistent treatment of cosmological structure formation and expansion within the context of classical general relativity may lead to "extra" expansion above that expected in…
Mass function of galaxy clusters in relativistic inhomogeneous cosmology
Jan J. Ostrowski, Thomas Buchert, Boudewijn F. Roukema
The current cosmological model (CDM) with the underlying FLRW metric relies on the assumption of local isotropy, hence homogeneity of the Universe. Difficulties arise when one a…
Model-independent analyses of non-Gaussianity in Planck CMB maps using Minkowski Functionals
Thomas Buchert, Martin J. France, Frank Steiner
Despite the wealth of results, there are difficulties in disentangling the primordial non-Gaussianity of the Cosmic Microwave Background (CMB) from the secondary and the f…
