Theoretical Priors and the Dark Energy Equation of State
Ido Ben-Dayan, Utkarsh Kumar
We revisit the theoretical priors used for inferring Dark Energy (DE) parameters. Any DE model must have some form of a tracker mechanism such that it behaved as matter or radiatio…

Emergent Unparticles Dark Energy can restore cosmological concordance
Ido Ben-Dayan, Utkarsh Kumar
Addressing the discrepancy between the late and early time measurements of the Hubble parameter, , and the so-called parameter has been a challenge in precision cosmolog…

Small Field models with ACTPol and BICEP3 data -- Likelihood analysis
Ira Wolfson, Utkarsh Kumar, Ido Ben-Dayan +1
We perform a Bayesian analysis for small field models of inflation, using the most recent datasets produced by Planck`18, ACTPol, and BICEP3. We employ Artificial Neural Networks (…
