Constraints on Ultra-Light Axions from the DESI DR1 Full Shape, Planck and ACT
Francesco Verdiani, Emanuele Castorina, Ennio Salvioni +2
The paper derives new limits on ultra-light axions as a small part of dark matter using galaxy clustering data from DESI DR1 together with CMB measurements from Planck and ACT.
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-…
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…
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…
