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…
Hermann Hankel's "On the general theory of motion of fluids", an essay including an English translation of the complete Preisschrift from 1861
Barbara Villone, Cornelius Rampf
The present is a companion paper to "A contemporary look at Hermann Hankel's 1861 pioneering work on Lagrangian fluid dynamics" by Frisch, Grimberg and Villone (2017). Here we pres…
Interacting neutrinos in cosmology: exact description and constraints
Isabel M. Oldengott, Thomas Tram, Cornelius Rampf +1
We consider the impact of neutrino self-interactions described by an effective four-fermion coupling on cosmological observations. Implementing the exact Boltzmann hierarchy for in…
How smooth are particle trajectories in a CDM Universe?
Cornelius Rampf, Barbara Villone, Uriel Frisch
It is shown here that in a flat, cold dark matter (CDM) dominated Universe with positive cosmological constant (), modelled in terms of a Newtonian and collisionless fluid, part…
