The World Cup. I. Summary of the baseline group stage results
Nils Schöneberg, Vivian Poulin, Angelo G. Ferrari +6
The Hubble tension has reached a nominal significance above , while new high-precision measurements of the cosmic microwave background (CMB) and baryon acoustic oscillations (B…
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…
