Dark energy perturbations in -body simulations
Jeppe Dakin, Steen Hannestad, Thomas Tram +2
We present -body simulations which are fully compatible with general relativity, with dark energy consistently included at both the background and perturbation level. We test ou…
Fully relativistic treatment of light neutrinos in -body simulations
Thomas Tram, Jacob Brandbyge, Jeppe Dakin +1
Cosmological -body simulations are typically purely run with particles using Newtonian equations of motion. However, such simulations can be made fully consistent with general r…
Momentum space sampling of neutrinos in -body simulations
Jacob Brandbyge, Steen Hannestad, Thomas Tram
Including massive neutrinos in -body simulations is a challenging task due to the large thermal velocities of the neutrinos. In particle based codes this leads to problems of sh…
Testing the Cosmic Shear Spatially-Flat Universe Approximation with Generalized Lensing and Shear Spectra
Peter L. Taylor, Thomas D. Kitching, Jason D. McEwen +1
We introduce the Generalised Lensing and Shear Spectra GLaSS code which is available for download from https://github.com/astro-informatics/GLaSS It is a fast and flexible public c…
: Cosmological neutrino simulations from the non-linear Boltzmann hierarchy
Jeppe Dakin, Jacob Brandbyge, Steen Hannestad +2
In this paper the non-linear effect of massive neutrinos on cosmological structures is studied in a conceptually new way. We have solved the non-linear continuity and Euler equatio…
Methods for studying the accuracy of light propagation in N-body simulations
S. M. Koksbang, S. Hannestad
It is proposed to use exact, cosmologically relevant solutions to Einstein's equations to accurately quantify the precision of ray tracing techniques through Newtonian N-body simul…
