A Relativistic view on large scale N-body simulations
Cornelius Rampf, Gerasimos Rigopoulos, Wessel Valkenburg
We discuss the relation between the output of Newtonian N-body simulations on scales that approach or exceed the particle horizon to the description of General Relativity. At leadi…
Relativistic Lagrangian displacement field and tensor perturbations
Cornelius Rampf, Alexander Wiegand
We investigate the purely spatial Lagrangian coordinate transformation from the Lagrangian to the basic Eulerian frame. We demonstrate three techniques for extracting the relativis…
Boltzmann hierarchy for interacting neutrinos I: formalism
Isabel M. Oldengott, Cornelius Rampf, Yvonne Y. Y. Wong
Starting from the collisional Boltzmann equation, we derive for the first time and from first principles the Boltzmann hierarchy for neutrinos including interactions with a scalar…
Astrophysical Bose-Einstein Condensates and Superradiance
Florian Kuhnel, Cornelius Rampf
We investigate gravitational analogue models to describe slowly rotating objects (e.g., dark-matter halos, or boson stars) in terms of Bose-Einstein condensates, trapped in their o…
