Cosmological Perturbation Theory for streams of relativistic particles
Hélène Dupuy, Francis Bernardeau
Motion equations describing streams of relativistic particles and their properties are explored in detail in the framework of Cosmological Perturbation Theory. Those equations, der…
Response function of the large-scale structure of the universe to the small scale inhomogeneities
Takahiro Nishimichi, Francis Bernardeau, Atsushi Taruya
In order to infer the impact of the small-scale physics to the large-scale properties of the universe, we use a series of cosmological -body simulations of self-gravitating matt…
Regularized cosmological power spectrum and correlation function in modified gravity models
Atsushi Taruya, Takahiro Nishimichi, Francis Bernardeau +2
Based on the multi-point propagator expansion, we present resummed perturbative calculations for cosmological power spectra and correlation functions in the context of modified gra…
