Modelling the Accelerating Universe with $f(Q)$ Gravity: Observational Consistency

Understand

In this paper, we present a cosmological model within the framework of symmetric teleparallel gravity, focusing on $f(Q)$ gravity, where $Q$ represents the non-metricity scalar.

• Utilizing cosmological datasets, we derive an accelerating cosmological model by constraining its free parameters.
• To achieve this, we determine the parametric form of the Hubble parameter using a well-motivated $f(Q)$ function.
• Remarkably, all obtained values fall within the range suggested by cosmological observations.
