Modified Emergent Dark Energy and its Astronomical Constraints
H. B. Benaoum, Weiqiang Yang, Supriya Pan +1
We introduce a modified form of the Phenomenologically Emergent Dark Energy (PEDE) model by showing a very elegant approach. The model is named as Modified Emergent Dark Energy (ME…
Dynamical Dark sectors and Neutrino masses and abundances
Weiqiang Yang, Eleonora Di Valentino, Olga Mena +1
We investigate generalized interacting dark matter-dark energy scenarios with a time-dependent coupling parameter, allowing also for freedom in the neutrino sector. The models are…
Nonlinear interacting cosmological models after Planck 2018 legacy release and the tension
Supriya Pan, Weiqiang Yang, Andronikos Paliathanasis
Interacting dark energy models are widely renowned for giving an explanation to the cosmic coincidence problem as well as several observational issues. According to the recent obse…
All-inclusive interacting dark sector cosmologies
Weiqiang Yang, Eleonora Di Valentino, Olga Mena +2
In this paper we explore possible extensions of Interacting Dark Energy cosmologies, where Dark Energy and Dark Matter interact non-gravitationally with one another. In particular,…
Understanding the phenomenology of interacting dark energy scenarios and their theoretical bounds
Supriya Pan, Jaume de Haro, Weiqiang Yang +1
Non-gravitational interaction between dark matter and dark energy has been considered in a spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) universe. The interaction rate…
Metastable dark energy models in light of Planck 2018: Alleviating the tension
Weiqiang Yang, Eleonora Di Valentino, Supriya Pan +2
We investigate the recently introduced metastable dark energy (DE) models after the final Planck 2018 legacy release. The essence of the present work is to analyze their evolution…
