Reconstruction of the quintessence dark energy potential from a Gaussian process

Understand

The quintessence dark energy potential is reconstructed in a model-independent way.

• Reconstruction relies on a Gaussian process and on available expansion-rate data.
• Specifically, 40-point values of $H(z)$ are used, consisting of a 30-point sample deduced from a differential age method and an additional 10-point sample obtained from the radial BAO method.
• Results are obtained for two kernel functions and for three different values of $H_{0}$.
