Fitting NANOGrav 15-year data and ACT data with modified inflation in entropic cosmology
Simone D'Onofrio, Sergei Odintsov, Tanmoy Paul
Recent evidences of stochastic gravitational wave background (SGWB) through Pulsar Time Array (PTA) observations hint towards an alternative inflationary scenario, compared to the…

I-Love-Q relations for Neutron Stars with Dark Energy
Simone D'Onofrio
The influence of a dark energy fluid on the equation of state of neutron stars is investigated. A detailed analysis is conducted for such models, including the computation of the m…

Generalized entropic dark energy with spatial curvature
Sergei D. Odintsov, Simone D'Onofrio, Tanmoy Paul
In the realm of thermodynamics of apparent horizon, we construct a dark energy (DE) model from 4-parameter generalized entropy of apparent horizon in a spatially non-flat universe.…
