Interacting Dark Energy in a closed universe
Eleonora Di Valentino, Alessandro Melchiorri, Olga Mena +2
Recent measurements of the Cosmic Microwave Anisotropies power spectra measured by the Planck satellite show a preference for a closed universe at more than Confidence Leve…
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…
Cosmology Intertwined IV: The Age of the Universe and its Curvature
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +88
A precise measurement of the curvature of the Universe is of primeval importance for cosmology since it could not only confirm the paradigm of primordial inflation but also help in…
Cosmology Intertwined III: and
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +89
The standard Cold Dark Matter cosmological model provides a wonderful fit to current cosmological data, but a few tensions and anomalies became statistically significant with t…
Cosmology Intertwined II: The Hubble Constant Tension
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +90
The current cosmological probes have provided a fantastic confirmation of the standard Cold Dark Matter cosmological model, that has been constrained with unprecedented accurac…
Cosmology Intertwined I: Perspectives for the Next Decade
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +89
The standard Cold Dark Matter cosmological model provides an amazing description of a wide range of astrophysical and astronomical data. However, there are a few big open quest…
Do current observations support transient acceleration of our universe?
Yu. L. Bolotin, V. A. Cherkaskiy, M. I. Konchatnyi +2
In the present article we have investigated a very natural question regarding the dynamics of the universe, namely, the possibility of its decelerating phase immediately after the…
Emergent Dark Energy, neutrinos and cosmological tensions
Weiqiang Yang, Eleonora Di Valentino, Supriya Pan +1
The Phenomenologically Emergent Dark Energy model, a dark energy model with the same number of free parameters as the flat CDM, has been proposed as a working example of a minim…
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…
Field theoretic interpretations of interacting dark energy scenarios and recent observations
Supriya Pan, German S. Sharov, Weiqiang Yang
Cosmological models describing the non-gravitational interaction between dark matter and dark energy are based on some phenomenological choices of the interaction rates between dar…
Forecast constraints on Anisotropic Stress in Dark Energy using gravitational-waves
Weiqiang Yang, Supriya Pan, David F. Mota +1
It is always interesting to investigate how well can a future experiment perform with respect to others (present or future ones). Cosmology is really an exciting field where a lot…
