Slow-rolling down the curvature: a reassessment of the Planck constraints on $ϕ^{2}$ inflation in a closed universe

Enrico Specogna, Tatevik Vardanyan, William Giarè +1

We revisit the Cosmic Microwave Background (CMB) constraints on the spatial curvature of the Universe, assessing how they change when the curvature parameter and the primordial inf…

Matter-antimatter asymmetry in a rotating universe: Dirac spinors in axisymmetric Bianchi IX cosmology

Tatevik Vardanyan

The standard $Λ$ CDM model, based on a highly symmetric FLRW geometry, successfully explains many observations but faces unresolved issues, motivating the exploration of alternative…
