چکیده

Abstract We further investigate the dark energy model based on Finsler geometry inspired osculating Barthel–Kropina cosmology. The cosmological approach is introduction of a Barthel connection in an geometry, with having property that it Levi-Civita Riemannian metric. From generalized Friedmann equations model, obtained by assuming background metric Friedmann–Lemaitre–Robertson–Walker type, effective geometric component can be generated, effective, type pressure, satisfying linear barotropic equation state. tests, and comparisons observational data this are considered detail. To constrain parameters, parameter state, we use 57 Hubble points, Pantheon Supernovae Type Ia sample. st statistical analysis performed using Markov Chain Monte Carlo (MCMC) simulations. A detailed comparison standard $$\Lambda $$ ? CDM also performed, Akaike information criterion (AIC), Bayesian (BIC) used as two selection tools. statefinder diagnostics consisting jerk snap Om ( z ) for comparative study cosmologies. Our results indicate gives good description data, thus viable alternative model.

Gravitational Energy as Dark Energy: Concordance of Cosmological Tests

We provide quantitative evidence that a new solution to averaging the observed inhomogeneous structure of matter in the universe (Wiltshire 2007a,b), leads to an observationally viable cosmology without exotic dark energy. We find concordance parameters which simultaneously satisfy three independent tests: the match to the angular scale of the sound horizon detected in the cosmic microwave back...

The Cosmological Dynamics of Interacting Holographic Dark Energy Model

Motivated by the recent observations for the cosmic acceleration and the suitable evolution of the Universe provided an interaction (decay of dark energy to matter) is incorporated in a cosmological model, we study the cosmological evolution of the Interacting Holographic Dark Energy scenario. Critical points are derived and their corresponding cosmological models are presented. The dynamical c...

The Cosmological Constant and Dark Energy

Physics invites the idea that space contains energy whose gravitational effect approximates that of Einstein’s cosmological constant, Λ; nowadays the concept is termed dark energy or quintessence. Physics also suggests the dark energy could be dynamical, allowing the arguably appealing picture that the dark energy density is evolving to its natural value, zero, and is small now because the expa...

Lemaître Class Dark Energy Model for Relaxing Cosmological Constant

Cosmological constant corresponds to the maximally symmetric cosmological term with the equation of state p = −ρ. Introducing a cosmological term with the reduced symmetry, pr = −ρ in the spherically symmetric case, makes cosmological constant intrinsically variable component of a variable cosmological term which describes time-dependent and spatially inhomogeneous vacuum dark energy. Relaxatio...
