Forecasting neutrino mass constraints from the Nancy Grace Roman Space Telescope
Francesco Spezzati, Yun Wang, Andrew Hearin
We present realistic forecasts for the constraining power of the Nancy Grace Roman Space Telescope on fundamental cosmological parameters, with particular emphasis on the absolute…
Equivalence of the field-level inference and conventional analyses on large scales
Francesco Spezzati, Marco Marinucci, Marko SimonoviÄ
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…
Observed unequal-time power spectrum
Francesco Spezzati, Eleonora Vanzan, Alvise Raccanelli +2
The next generation of galaxy surveys will provide highly precise measurements of galaxy clustering, therefore requiring a corresponding accuracy. Current approaches, which rely on…
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…
3D-Radial galaxy correlation function
Francesco Spezzati, Alvise Raccanelli
Tests of cosmological models via measurements of galaxy correlations will require increasing modeling accuracy, given the high precision of measurements promised by forthcoming gal…
