The thawing dark energy dynamics: Can we detect it?

Understand

We consider different classes of scalar field models including quintessence, and tachyon scalar fields with a variety of generic potential belonging to thawing type.

• Assuming the scalar field is initially frozen at $w=-1$, we evolve the system until the present time.
• We focus on observational quantities like Hubble parameter, luminosity distance as well as quantities related to the Baryon Acoustic Oscillation measurement.
• Our study shows that with present state of observations, one can not distinguish amongst various models which in turn can not be distinguished from cosmological constant.
