The dark matter bispectrum from effective viscosity and one-particle irreducible vertices
Stefan Floerchinger, Mathias Garny, Aris Katsis +2
Dark matter evolution during the process of cosmological structure formation can be described in terms of a one-particle irreducible effective action at a characteristic scale $k_m…
Effective description of dark matter as a viscous fluid
S. Floerchinger, M. Garny, N. Tetradis +1
Treating dark matter at large scales as an effectively viscous fluid provides an improved framework for the calculation of the density and velocity power spectra compared to the st…
Renormalization-group flow of the effective action of cosmological large-scale structures
Stefan Floerchinger, Mathias Garny, Nikolaos Tetradis +1
Following an approach of Matarrese and Pietroni, we derive the functional renormalization group (RG) flow of the effective action of cosmological large-scale structures. Perturbati…
Large scale structure from viscous dark matter
Diego Blas, Stefan Floerchinger, Mathias Garny +2
Cosmological perturbations of sufficiently long wavelength admit a fluid dynamic description. We consider modes with wavevectors below a scale for which the dynamics is only…
