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…
Galaxy bispectrum, primordial non-Gaussianity and redshift space distortions
Matteo Tellarini, Ashley J. Ross, Gianmassimo Tasinato +1
Measurements of the non-Gaussianity of the primordial density field have the power to considerably improve our understanding of the physics of inflation. Indeed, if we can increase…
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…
The Open Universe Grishchuk-Zel'dovich Effect
Juan Garcia-Bellido, Andrew R Liddle, David H Lyth +1
The Grishchuk--Zel'dovich effect is the contribution to the microwave background anisotropy from an extremely large scale adiabatic density perturbation, on the standard hypothesis…
Low energy effective string cosmology
E. J. Copeland, Amitabha Lahiri, David Wands
We give the general analytic solutions derived from the low energy string effective action for four dimensional Friedmann-Robertson-Walker models with dilaton and antisymmetric ten…
