The World Cup. I. Summary of the baseline group stage results
Nils Schöneberg, Vivian Poulin, Angelo G. Ferrari +6
The paper evaluates fourteen extensions to the standard ΛCDM cosmology against recent CMB, BAO, and supernova data to see which can reduce the Hubble‑constant tension, finding that…
Effective Field Theory of Large Scale Structure and Newtonian Motion Gauges
Christian Fidler, Julien Lesgourgues, Antonia Mattes +2
The simplest flavor of the Effective Field Theory of Large Scale Structure is based on Newtonian equations and describes the nonlinear matter density and velocity using Einstein-de…
Euclid preparation: Testing multi-field inflation with galaxy power spectrum and bispectrum
Euclid Collaboration, D. Linde, A. Moradinezhad Dizgah +281
Primordial non-Gaussianity (PNG) is a powerful probe of the origin of cosmic structure. Stage-IV surveys like \Euclid will measure galaxy - and -point clustering at high sign…
Recoupled Dark Radiation reconciling CMB and DESI BAO measurements
Ravi Kumar Sharma, Maria Archidiacono, Julien Lesgourgues
Recent DESI BAO measurements, combined with CMB data, reveal a tension within the CDM model that leads to a discrepancy between cosmological and laboratory bounds on the summed…
