Redshift-space distortions in massive neutrinos cosmologies
Francesco Verdiani, Emilio Bellini, Chiara Moretti, E. Sefusatti, Carmelita Carbone, Matteo Viel
Izvirni znanstveni članek
Oznake: cosmology;neutrinos;large-scale structure;power spectrum;galaxy surveys;
We study the Kaiser formula for biased tracers in massive neutrino cosmologies by comparing its predictions with a large set of N-body simulations. In particular, we examine the ambiguity in the definition of the peculiar velocity contribution at linear level, whether it should be expressed in terms ...

Reconstructing the dark energy density in light of DESI BAO observations
Maria Berti, Emilio Bellini, Camille Bonvin, Martin Kunz, Matteo Viel, Miguel Zumalacarregui
Izvirni znanstveni članek
Oznake: alternative gravity theories;cosmology;dark energy;evolution of the universe;large scale structure of the universe;
In light of the evidence for dynamical dark energy (DE) found from the most recent Dark Energy Spectroscopic Instrument (DESI) baryon acoustic oscillation (BAO) measurements, we perform a nonparametric, model-independent reconstruction of the DE density evolution. To do so, we develop and validate a ...
