Relativistic Interpretation of Newtonian Simulations for Cosmic Structure Formation
Christian Fidler, Thomas Tram, Cornelius Rampf +3
The standard numerical tools for studying non-linear collapse of matter are Newtonian -body simulations. Previous work has shown that these simulations are in accordance with Ge…
The Intrinsic Matter Bispectrum in CDM
Thomas Tram, Christian Fidler, Robert Crittenden +3
We present a fully relativistic calculation of the matter bispectrum at second order in cosmological perturbation theory assuming a Gaussian primordial curvature perturbation. For…
A new line-of-sight approach to the non-linear Cosmic Microwave Background
Christian Fidler, Kazuya Koyama, Guido W. Pettinari
We develop the transport operator formalism, a new line-of-sight integration framework to calculate the anisotropies of the Cosmic Microwave Background (CMB) at the linear and non-…
