SSFDE Model: Cosmological Implications and Dynamical System Analysis
Ritika Nagpal, Anil Kandel, Ratul Mandal +2
In this paper, we consider an interacting scalar field dark energy model with an exponential potential and a dark sector coupling \( Q = 3γHρ_{dm} \), which has been observationall…

Dark Sector Interactions: Probing the Hubble Parameter and the Sound Horizon
Ritika Nagpal, S. K. J. Pacif, Farruh Atamurotov +1
In this study, we explore the impact of the interacting parameter on dark matter in a model resulting from a parametrization of dark energy density. To ensure a model-independent a…
