dc.description.abstract
The Cosmological Boundary Flux Parameter is a novel proposal that attempts to explain the origin of the cosmological parameter Λ purely by geometric nature. Then we implement this new approach to a flat FLRW universe along with a barotropic fluid. We present an ansatz in which Λ is straightforwardly coupled to the matter sector; therefore, only one additional parameter was introduced: λ. Also, through a statistical analysis, using late-time data of observational Hubble and type Ia Supernovae, we computed the joint best-fit value of the free parameters by means of the affine-invariant MCMC. We want to emphasise that the joint analysis produces a smaller H0CBFP=69.80Kms−1Mpc−1 in contrast to the flat ΛCDM result H0ΛCDM=70.53Kms−1Mpc−1. The work presented here seeks to contribute to the discussion of the possible explanation for the cosmos’ acceleration, together with tackling other important questions in modern cosmology.
