Abstract
This article introduces a novel parametric form of the Hubble parameter for exploring the accelerating cosmos in a model-independent manner. The model parameters are constrained using a Markov Chain Monte Carlo (MCMC) approach with a combined dataset spanning 31 cosmic chronometers (CC) data points, 26 non-correlated baryonic acoustic oscillations (BAO) points, and 1701 updated Pantheon+ supernovae type Ia (SNeIa) data points. We investigate the model’s kinematic behavior, including the transition from the deceleration phase to the acceleration phase, the jerk evolution, and the energy conditions. The results of the equation of state parameter suggest that our model behaves like the quintessence model and supports the current accelerating Universe. Additionally, we impose constraints on both the model parameters and the Hubble constant H0, and find that the values obtained for H0 align with other works obtained through reconstruction methods and observational data. Overall, this study provides valuable insights into the accelerating cosmos and highlights the importance of a model-independent approach in cosmological studies.
