CMB anisotropies from patchy reionisation and diffuse Sunyaev-Zel'dovich effects
Christian Fidler, Christophe Ringeval
Anisotropies in the Cosmic Microwave Background (CMB) can be induced during the later stages of cosmic evolution, and in particular during and after the Epoch of Reionisation. Inho…
General relativistic weak-field limit and Newtonian N-body simulations
Christian Fidler, Thomas Tram, Cornelius Rampf +3
We show how standard Newtonian N-body simulations can be interpreted in terms of the weak-field limit of general relativity by employing the recently developed Newtonian motion gau…
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…
Relativistic initial conditions for N-body simulations
Christian Fidler, Thomas Tram, Cornelius Rampf +3
Initial conditions for (Newtonian) cosmological N-body simulations are usually set by re-scaling the present-day power spectrum obtained from linear (relativistic) Boltzmann codes…
Kinetic theory of fermions in curved spacetime
Christian Fidler, Cyril Pitrou
We build a statistical description of fermions, taking into account the spin degree of freedom in addition to the momentum of particles, and we detail its use in the context of the…
