3D simulations with boosted primordial power spectra and ultracompact minihalos
Mateja Gosenca, Julian Adamek, Christian T. Byrnes +1
We perform three-dimensional simulations of structure formation in the early Universe, when boosting the primordial power spectrum on approximately kpc scales. We demonstrate that…
Perturbed redshifts from N-body simulations
Julian Adamek
In order to keep pace with the increasing data quality of astronomical surveys the observed source redshift has to be modeled beyond the well-known Doppler contribution. In this le…
Relativistic N-body simulations with massive neutrinos
Julian Adamek, Ruth Durrer, Martin Kunz
Some of the dark matter in the Universe is made up of massive neutrinos. Their impact on the formation of large scale structure can be used to determine their absolute mass scale f…
Safely smoothing spacetime: backreaction in relativistic cosmological simulations
Julian Adamek, Chris Clarkson, David Daverio +2
A persistent theme in the study of dark energy is the question of whether it really exists or not. It is often claimed hat we are mis-calculating the cosmological model by neglecti…
The effect of early radiation in N-body simulations of cosmic structure formation
Julian Adamek, Jacob Brandbyge, Christian Fidler +3
Newtonian N-body simulations have been employed successfully over the past decades for the simulation of the cosmological large-scale structure. Such simulations usually ignore rad…
