We compare a large suite of theoretical cosmological models to observational data from the
cosmic microwave background, baryon acoustic oscillation measurements of expansion …

The coupling between the dark components provides a new approach to mitigate the
coincidence problem of cosmological standard model. In this paper, dark energy is treated …

We investigate the cosmological constraints on sterile neutrinos in a universe in which
vacuum energy interacts with cold dark matter by using latest observational data. We focus …

In this paper, we investigate the observational constraints on the scenario of vacuum energy
interacting with cold dark matter. We consider eight typical interaction forms in such an …

In this paper, we consider three phantom dark energy models, in the context of interaction
between the dark components namely cold dark matter (CDM) and dark energy (DE). The …

We study the cosmological consequences of interacting Tsallis holographic dark energy
model in the framework of the fractal universe in which the Hubble radius is considered as …

Yes, but only for a parameter value that makes it almost coincide with the standard model.
We reconsider the cosmological dynamics of a generalized Chaplygin gas (gCg) which is …

The coupling between dark sectors provides a possible approach to mitigate the
coincidence problem of the cosmological standard model. In this paper, dark energy is …

Recent measurements of the cosmic microwave background (CMB) by the Planck
Collaboration have produced arguably the most powerful observational evidence in support …

We present improved constraints on an interacting vacuum model using updated
astronomical observations including the first data release from Planck. We consider a model …
