Dark calling Dark: Interaction in the dark sector in presence of neutrino properties after Planck CMB final release
Weiqiang Yang, Supriya Pan, Rafael C. Nunes +1
We investigate a well known scenario of interaction in the dark sector where the vacuum energy is interacting with cold dark matter throughout the cosmic evolution in light of the…
Reconciling tension in a six parameter space?
Supriya Pan, Weiqiang Yang, Eleonora Di Valentino +2
Consistent observations indicate that some of the important cosmological parameters measured through the local observations are in huge tension with their measurements from the glo…
Interacting scenarios with dynamical dark energy: observational constraints and alleviation of the tension
Supriya Pan, Weiqiang Yang, Eleonora Di Valentino +2
We investigate interacting scenarios which belong to a wider class, since they include a dynamical dark energy component whose equation of state follows various one-parameter param…
Dawn of the dark: unified dark sectors and the EDGES Cosmic Dawn 21-cm signal
Weiqiang Yang, Supriya Pan, Sunny Vagnozzi +3
While the origin and composition of dark matter and dark energy remains unknown, it is possible that they might represent two manifestations of a single entity, as occurring in uni…
Dark sectors with dynamical coupling
Weiqiang Yang, Olga Mena, Supriya Pan +1
Coupled dark matter-dark energy scenarios are modeled via a dimensionless parameter , which controls the strength of their interaction. While this coupling is commonly assumed t…
Challenging bulk viscous unified scenarios with cosmological observations
Weiqiang Yang, Supriya Pan, Eleonora Di Valentino +2
In a spatially flat Friedmann-Lemaître-Robertson-Walker universe, we investigate a unified cosmic fluid scenario endowed with bulk viscosity in which the coefficient of the bulk vi…
