Probing dark energy dynamics through a new CPL-type parametrization in FLRW Universe
D. Revanth Kumar, Santosh Kumar Yadav, S. A. Kadam
In this work, we investigate a CPL-type parametrization given by to study the evolution of dark energy and possible deviations from th…

Constraining Dark Energy Dynamics in Curved Spacetime with Current Observations
D. Revanth Kumar, Santosh Kumar Yadav
We investigate a dark energy (DE) equation of state (EoS) parametrization in a curved spacetime using current observations. We constrain the model parameters by using observational…

Observational tests of \texorpdfstring{}{Lambda(t)} cosmology in light of DESI DR2
D. Revanth Kumar, Santosh Kumar Yadav, S. A. Kadam
In this article, we investigate two phenomenological decaying vacuum cosmological models describing the accelerated expansion of the Universe. We constrain the model parameters usi…
