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, with the latter lying at roughly the level fr…

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…

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…
