The world cup. II. A comprehensive competition between proposed Hubble tension solutions
Nils Schöneberg, Vivian Poulin, Angelo G. Ferrari +6
The paper systematically compares fourteen proposed solutions to the Hubble tension using a common set of CMB, BAO, and supernova data, evaluating their performance with Bayesian a…
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…
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…
Forecasting Constraints on Non-Thermal Light Massive Relics from Future CMB Experiments (CMB-S4/Simons Observatory)
Arka Banerjee, Abhik Bhattacharjee, Subinoy Das +2
In this work we present Fisher forecasts on \textit{non-thermal LiMR} models for a CMB Stage IV-like experiment and the Simons Observatory -- particularly focusing on a model of in…
