The world cup. II. A comprehensive competition between proposed Hubble tension solutions
Nils Schöneberg, Vivian Poulin, Angelo G. Ferrari +6
Cosmology stands at a crossroads. The Hubble tension has reached a nominal significance above , while analyses combining DESI BAO and Type Ia supernova data show emerging hints…
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…
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…
Early Dark Energy beyond slow-roll: implications for cosmic tensions
Ravi Kumar Sharma, Subinoy Das, Vivian Poulin
In this work, we explore the possibility that Early Dark Energy (EDE) is dynamical in nature and study its effect on cosmological observables. We introduce a parameterization of th…
Non-thermal warm dark matter limits from small-scale structure
Arka Banerjee, Subinoy Das, Anshuman Maharana +2
We present small-scale structure constraints on sterile dark matter produced from a heavy mediator particle, inspired by models of moduli decay. Dark matter particles produced thro…
Signatures of Light Massive Relics on nonlinear structure formation
Arka Banerjee, Subinoy Das, Anshuman Maharana +1
Cosmologies with Light Massive Relics (LiMRs) as a subdominant component of the dark sector are well-motivated from a particle physics perspective, and can also have implications f…
Implications of an extended dark energy model with massive neutrinos
Ravi Kumar Sharma, Kanhaiya Lal Pandey, Subinoy Das
Recently there has been reports of finding a lower bound on the neutrino mass parameter () when using ACT and SPTpol data however these bounds on the are still weaker…
Non-thermal neutrino-like hot dark matter in light of the tension
Subinoy Das, Anshuman Maharana, Vivian Poulin +1
The CDM prediction of -- where is the root mean square of matter fluctuations on a 8 Mpc scale -- once calibrated on Planck CMB data…
