“…Observational evidence has been found of the interaction between dark energy and dark matter from the Abell Cluster A586 [26]. Observations by [27,28,29] indicate the possibility of the decay of dark matter into dark energy and more recently [30] analyze linear cosmological interaction with Planck data and conclude that the interaction is compatible with the latest and more precise observations. It is noteworthy to mention that they obtain slightly negative interaction in some cases.…”

In a flat Friedmann-Lemaître-Robertson-Walker background, a scheme of dark matterdark energy interaction is studied considering a holographic Ricci-like model for the dark energy. Without giving a priori some specific model for the interaction function, we show that this function can experience a change of sign during the cosmic evolution. The parameters involved in the holographic model are adjusted with Supernova data and we obtained results compatible with the observable universe.

“…For instance, Costa et al (2016) made updated constraints for IwCDM1 and IwCDM2 by using the Planck+BAO+SNIa+RSD+H0 data. In this paragraph, Planck denotes Planck 2015 CMB data instead of the distance priors; BAO denotes the isotropic 6dFGS, MGS, BOSS DR11 LOWZ and CMASS; the value of H0 is lower than the report of Riess et al (2016).…”

The local measurement of H 0 is in tension with the prediction of ΛCDM model based on the Planck data. This tension may imply that dark energy is strengthened in the late-time Universe. We employ the latest cosmological observations on CMB, BAO, LSS, SNe, H(z) and H 0 to constrain several interacting dark energy models. Our results show no significant indications for the interaction between dark energy and dark matter. The H 0 tension can be moderately alleviated, but not totally released.

“…IV, baryons, DM and DE interact only indirectly by gravitation (via the Poisson equation). However, DE may interact with DM non-gravitationally, via a reciprocal exchange of energy and momentum; thus, is called interacting DE (IDE) [7,73,[109][110][111]. In this section we probe the magnification angular power spectrum for an IDE scenario-assuming (hereafter) a latetime universe dominated by DM and DE only.…”

Apart from the known weak gravitational lensing effect, the cosmic magnification acquires relativistic corrections owing to Doppler, integrated Sachs-Wolfe, time-delay and other (local) gravitational potential effects, respectively. These corrections grow on very large scales and high redshifts z, which will be the reach of forthcoming surveys. In this work, these relativistic corrections are investigated in the magnification angular power spectrum, using both (standard) noninteracting dark energy (DE), and interacting DE (IDE). It is found that for noninteracting DE, the relativistic corrections can boost the magnification large-scale power by ∼40% at z = 3, and increases at lower z. It is also found that the IDE effect is sensitive to the relativistic corrections in the magnification power spectrum, particularly at low z-which will be crucial for constraints on IDE. Moreover, the results show that if relativistic corrections are not taken into account, this may lead to an incorrect estimate of the large-scale imprint of IDE in the cosmic magnification; including the relativistic corrections can enhance the true potential of the cosmic magnification as a cosmological probe.
