Euclid preparation. Review of forecast constraints on dark energy and modified gravity
Euclid Collaboration, N. Frusciante, M. Martinelli +326
The Euclid mission has been designed to provide, as one of its main deliverables, information on the nature of the gravitational interaction, which determines the expansion of the…

Equivalence of the field-level inference and conventional analyses on large scales
Francesco Spezzati, Marco Marinucci, Marko Simonović
We study a simple setup with dark matter halos in real space, with the amplitude of the linear density field as the only free cosmological parameter. We show that Eulerian pert…

The constraining power of the Marked Power Spectrum: an analytical study
Marco Marinucci, Gabriel Jung, Michele Liguori +8
The marked power spectrum - a two-point correlation function of a transformed density field - has emerged as a promising tool for extracting cosmological information from the large…
