The cosmological standard model includes a dark sector in order to explain the current observations. This dark sector includes all the constituents of the universe that are not described by the standard model of particle physics, which presence is only inferred from gravitational interactions. The currently most accepted model introduces a cosmological constant to account for the late expansion of the universe and cold dark matter to explain the dynamics of the universe. These two components, along with the already known fields, constitute the CDM model, which successfully fits different cosmological observations at different scales. However, there is a lot of uncertainty concerning the fundamental properties of this dark sector…
