Exploring scalar field dynamics with Gaussian processes

Nair, Remya, Jhingan, Sanjay, Jain, Deepak

Understand

The origin of the accelerated expansion of the Universe remains an unsolved mystery in Cosmology.

In this work we consider a spatially flat Friedmann-Robertson-Walker (FRW) Universe with non-relativistic matter and a single scalar field contributing to the energy density of the Universe.
Properties of this scalar field, like potential, kinetic energy, equation of state etc.
are reconstructed from Supernovae and BAO data using Gaussian processes.
