Models where the dark matter component of the Universe interacts with the dark energy field have been proposed as a solution to the cosmic coincidence problem, since in the attractor regime both dark energy and dark matter ...

In this article, we aim to demystify the Deep Web and the Dark Web, in addition to presenting the main similarities and disparities between them, essentially in regard to their: (1)Term; (2) Definition; (3) Metaphorical ...

There are a plethora of dark energy parametrizations that can fit current supernovae Ia data. However, these data are only sensitive to redshifts up to order one. In fact, many of these parametrizations break down at higher ...

We examine a scenario where the Higgs boson is coupled to an additional Standard Model singlet scalar field from a hidden sector. We show that, in the case where this field is very light and has already relaxed to its ...

The observation of galaxy and gas distributions, as well as cosmological simulations in a Lambda CDM cold dark matter universe, suggests that clusters of galaxies are still accreting mass and are not expected to be in ...

Dark matter with strong self-interactions provides a compelling solution to several small-scale structure puzzles. Under the assumption that the coupling between dark matter and the Standard Model particles is suppressed, ...

Creation of Cold Dark Matter (CCDM), in the context of Einstein Field Equations, leads to a negative creation pressure, which can be used to explain the accelerated expansion of the Universe. Recently, it has been shown ...
