Gaussian process reconstruction of scalar field dynamics from recent cosmological data
Afaq Maqsood, Sonej Alam, Md. Wali Hossain
We reconstruct the late-time expansion history and dark energy dynamics using available cosmological data. We consider dark energy as an effective minimally coupled canonical scala…
A single field inflationary potential consistent with recent observations
Md. Wali Hossain
Current observations indicate that an inverse exponential form of the inflaton potential provides an excellent description of single-field inflation. This potential fits the SPA…
Probing the sensitivity of dark energy dynamics to equation of state parametrization flexibility
Md. Wali Hossain
Allowing for greater low redshift flexibility through parametrizations such as CPL can lead to apparent deviations from CDM. This motivates an investigation into whether such de…
Cosmological implications of tracker scalar fields: Testing the evidence for dynamical dark energy with recent data
Md. Wali Hossain, Afaq Maqsood
We investigate non phantom tracker scalar field models as dynamical dark energy scenario. These models can alleviate the cosmic coincidence problem and transition to a cosmological…
A comparison between axion-like and power law potentials in cosmological background
Md. Wali Hossain, Afaq Maqsood
In this paper, we compare the scalar field dynamics in axion-like and power law potentials for both positive and negative values of the exponents. We find that, for positive expone…
