Improving precision and accuracy in cosmology with model-independent spectrum and bispectrum
Luca Amendola, Marco Marinucci, Massimo Pietroni +1
A new and promising avenue was recently developed for analyzing large-scale structure data with a model-independent approach, in which the linear power spectrum shape is parametriz…
Euclid: Constraining linearly scale-independent modifications of gravity with the spectroscopic and photometric primary probes
N. Frusciante, F. Pace, V. F. Cardone +127
The future Euclid space satellite mission will offer an invaluable opportunity to constrain modifications to Einstein's general relativity at cosmic scales. We focus on modified gr…
Constraints on modified gravity from the BOSS galaxy survey
Lorenzo Piga, Marco Marinucci, Guido D'Amico +3
We develop a pipeline to set new constraints on scale-independent modified gravity, from the galaxy power spectrum in redshift space of BOSS DR12. The latter is modelled using the…
Fisher matrix for the one-loop galaxy power spectrum: measuring expansion and growth rates without assuming a cosmological model
Luca Amendola, Massimo Pietroni, Miguel Quartin
We introduce a methodology to extend the Fisher matrix forecasts to mildly non-linear scales without the need of selecting a cosmological model. We make use of standard non-linear…
The Large Scale Structure Bootstrap: perturbation theory and bias expansion from symmetries
Guido D'Amico, Marco Marinucci, Massimo Pietroni +1
We investigate the role played by symmetries in the perturbative expansion of the large-scale structure. In particular, we establish which of the coefficients of the perturbation t…
One-Dimensional Fuzzy Dark Matter Models: Structure Growth and Asymptotic Dynamics
Tim Zimmermann, Nico Schwersenz, Massimo Pietroni +1
This paper investigates the feasibility of simulating Fuzzy Dark Matter (FDM) with a reduced number of spatial dimensions. Our aim is to set up a realistic, yet numerically inexpen…
