Abstract Models where dark matter and dark energy interact with each other have been
proposed to solve the coincidence problem. We review the motivations underlying the need …

In this paper, we summarize some of the main observational challenges for the standard
Friedmann–Lemaître–Robertson–Walker (FLRW) cosmological model and describe how …

We consider the possibility of an interaction in the dark sector in the presence of massive
neutrinos and study the observational constraints on three different scenarios of massive …

We study a coupled quintessence model with pure momentum exchange and present the
effects of such an interaction on the cosmic microwave background (CMB) and matter power …

We use the latest compilation of observational Hubble parameter measurements estimated
with the differential evolution of cosmic chronometers, in combination with the local value of …

We investigate a phenomenological non-gravitational coupling between dark energy and
dark matter, where the interaction in the dark sector is parameterized as an energy transfer …

We perform a forecast analysis of the capability of the eLISA space-based interferometer to
constrain models of early and interacting dark energy using gravitational wave standard …

We test the models of vacuum energy interacting with cold dark matter and try to probe the
possible deviation from the Λ CDM model using current observations. We focus on two …

We review matter bounce scenarios where the matter content is dark matter and dark
energy. These cosmologies predict a nearly scale-invariant power spectrum with a slightly …

The local measurement of H 0 is in tension with the prediction of Λ cold dark matter model
based on the Planck data. This tension may imply that dark energy is strengthened in the …
