Perturbation theory of LSS in the CDM Universe: exact time evolution and the two-loop power spectrum
Matteo Fasiello, Tomohiro Fujita, Zvonimir Vlah
We derive exact analytic solutions for density and velocity fields to all orders in Eulerian standard perturbation theory for CDM cosmology. In particular, we show that density…
A Tale of Two Scales: Screening in Large Scale Structure
Matteo Fasiello, Zvonimir Vlah
The perturbative treatment of dark matter in structure formation relies on the existence of a well-defined expansion parameter, , with signalling the ons…
Screening in perturbative approaches to LSS
Matteo Fasiello, Zvonimir Vlah
A specific value for the cosmological constant, Λ, can account for late-time cosmic acceleration. However, motivated by the so-called cosmological constant problem(s), several alte…
On Observables in a Dark Matter-Clustering Quintessence System
Matteo Fasiello, Zvonimir Vlah
We consider a system where dark matter dynamics is enriched by the presence of clustering quintessence in the approximation where the system is effectively reduced to one degree of…
Non-linear Fields in Generalized Cosmologies
Matteo Fasiello, Zvonimir Vlah
The perturbative approach to structure formation has recently received a lot of attention in the literature. In such setups the final predictions for observables like the power spe…
