Probing General Relativity on Cosmological Scales in the 2040s
Federico Montano, Samantha J. Rossiter, Chris Addis +18
General relativity is exquisitely tested in strong-field regimes, yet its validity on cosmological scales remains largely unexplored. Upcoming wide and deep large-scale structure s…
Beyond Stage IV: Quasar and Galaxy Clustering and the Fundamental Physics of the 2040s
M. Guidi, M. Moresco, H. K. Herrera-Alcantar +24
Stage IV galaxy surveys (DESI, 4MOST, MOONS, Euclid) are establishing precision constraints on cosmological parameters through baryon acoustic oscillations and redshift-space disto…
Cosmological constraints from the angular power spectrum and bispectrum of luminous red galaxies and CMB lensing
Francesco Verdiani, Lea Harscouet, Matteo Zennaro +2
We study the projected clustering of photometric luminous red galaxies from the DESI Legacy Survey, combining their angular power spectrum, bispectrum, and cross-correlation with m…
The Effective Field Theory of Large Scale Structure for Mixed Dark Matter Scenarios
Francesco Verdiani, Emanuele Castorina, Ennio Salvioni +1
We initiate a systematic study of the perturbative nonlinear dynamics of cosmological fluctuations in dark sectors comprising a fraction of non-cold dark matter, for example ultra-…
Redshift-Space Distortions in Massive Neutrinos Cosmologies
Francesco Verdiani, Emilio Bellini, Chiara Moretti +3
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 am…
