Dissipative CDM model with causal sign-switching bulk viscous pressure

Vishnu A Pai, Sarath N, Titus K Mathew

Extending the standard CDM model by considering dissipative effects within a causal viscous framework, and obtaining an analytical solution for the Hubble parameter remains a ch…

On the Interrelation of the Generalized Holographic Equipartition and Entropy Maximization in Kaniadakis Paradigm

Pranav Prasanthan, Sarath Nelleri, Archana K Pradeepan +2

This study examines the compatibility of the generalized holographic equipartition proposed in ref \cite{sheykhi2013friedmann} with the maximization of horizon entropy in an (n + 1…

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 ()…

Emergence of Cosmic Space and Horizon Thermodynamics from Kaniadakis Entropy

Pranav Prasanthan, Sarath Nelleri, Navaneeth Poonthottathil +1

Utilizing Kaniadakis entropy associated with the apparent horizon of the Friedmann-Robertson-Walker (FRW) Universe and applying the emergence of cosmic space paradigm, we deduce th…

Scalar Field Dominated Cosmology with Woods-Saxon Like Potential

Sreerag Radhakrishnan, Sarath Nelleri, Navaneeth Poonthottathil

Dark energy can be characterized by a canonical scalar field, known as quintessence. Quintessence allows for a dynamical equation of state . A previous st…

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 CDM framework. In a recent s…
