Constraining Quintessence Models with ISW-tSZ Cross-Correlations: A Comparative Analysis of Thawing, Tracker, and Scaling-Freezing Dynamics
Ayodeji Ibitoye, Shiriny Akthar, Md. Wali Hossain +5
We present constraints on quintessence dark energy models using the observational detection of the Integrated Sachs-Wolfe (ISW)--thermal Sunyaev-Zeldovich (tSZ) cross-correlation d…
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…
General parametrization for energy density of quintessence field
Shiriny Akthar, Md. Wali Hossain
We present a general parametrization for energy density of a quintessence field, a minimally coupled canonical scalar field which rolls down slowly during the late time. This param…
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…
