Dark matter vorticity and velocity dispersion from truncated Dyson$\unicode{x2013}$Schwinger equations
Alaric Erschfeld, Stefan Floerchinger
Large-scale structure formation is studied in a kinetic theory approach, extending the standard perfect pressureless fluid description for dark matter by including the velocity dis…
Cosmological functional renormalisation group, extended Galilean invariance and the sweeping effect
Alaric Erschfeld, Stefan Floerchinger
The functional renormalisation group is employed to study the non-linear regime of late-time cosmic structure formation. This framework naturally allows for non-perturbative approx…
General relativistic non-ideal fluid equations for dark matter from a truncated cumulant expansion
Alaric Erschfeld, Stefan Floerchinger, Maximilian Rupprecht
A new truncation scheme based on the cumulant expansion of the one-particle phase-space distribution function for dark matter particles is developed. Extending the method of moment…
Evolution of dark matter velocity dispersion
Alaric Erschfeld, Stefan Floerchinger
Cosmological perturbation theory for the late Universe dominated by dark matter is extended beyond the perfect fluid approximation by taking the dark matter velocity dispersion ten…
