Observational constraints on early time non-phantom behaviour of dynamical dark energy
Sk. Sohail, Sonej Alam, Md. Wali Hossain
We investigate dynamical dark energy models that admit non-phantom behaviour at early times, including thawing, scaling--thawing, and effective fluid extensions. Using current cosm…

Quintessential early dark energy
Sk. Sohail, Sonej Alam, Shiriny Akthar +1
We introduce a unified model of early and late dark energy. We call it {\it quintessential early dark energy} model where early and late dark energy are explained by a single scala…
