Observational Evidence to Logistic Dark Energy Driving the Accelerating Universe

Sarath Nelleri, Gopi Krishna, Navaneeth Poonthottathil

We present logistic dark energy model (LDEM), where the dark energy density follows a logistic function for the scale factor. The equation of state parameter of dark energy ( $w_{D}$ )…

Observational evidence for parametrized emergent dark energy models

Sarath Nelleri, Navaneeth Poonthottathil

Recent cosmological observations show a statistically significant tension in the estimated values of the cosmological parameters within the standard $Λ$ CDM framework. In a recent s…

Testing the dynamical stability and validity of generalized second law within the phantom dynamical dark energy model

Naseeba. K. M, Sarath Nelleri, Navaneeth Poonthottathil

Hubble constant( $H_{0}$ ) tension and tension in the matter fluctuation amplitude ( $s_{8}$ ) are fascinating puzzles in cosmology nowadays. Phantom dynamical dark energy model (PDDE), al…
