Probing dark energy with braneworld cosmology in the light of recent cosmological data

Understand

We investigate a brane model based on Randall-Sundrum scenarios with a generic dark energy component.

• The latter drives the accelerated expansion at late times of the Universe.
• In this scheme, extra terms are added into Einstein Field equations that are propagated to the Friedmann equations.
• To constrain the dark energy equation of state (EoS) and the brane tension we use observational data with different energy levels (Supernovae type Ia, $H(z)$, baryon acoustic oscillations, and cosmic microwave background radiation distance, and a joint analysis) in a background cosmology.
