General Relativistic Entropic Acceleration at the perturbation level: a CLASS implementation and first Boltzmann-code constraints
Simone D'Onofrio, Dong Ha Lee, Eleonora Di Valentino +1
General Relativistic Entropic Acceleration (GREA) attributes the late-time acceleration of the Universe to the entropy growth of the causal cosmological horizon, without a cosmolog…
Axial tidal Love numbers of black holes in matter environments
Simone D'Onofrio, Sayak Datta, Andrea Maselli
We study the axial (magnetic) tidal Love numbers of a Schwarzschild black hole surrounded by a spherically symmetric matter distribution. While the formalism developed here is gene…
Exponential cosmology with massive neutrinos as a dynamical dark energy framework
Simone D'Onofrio, Sergei Odintsov, Tiziano Schiavone
The exponential gravity model provides a theoretically well-motivated extension of General Relativity, introducing a modified gravitational dynamics at late times consistent…
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.…
Primordial gravitational waves in horizon cosmology and constraints on entropic parameters
Sergei D. Odintsov, Simone D'Onofrio, Tanmoy Paul
The hallmark of the 4-parameter generalized entropy is that it can represent various known entropies proposed so far for suitable limits of the parameters, and thus the 4-parameter…
Entropic Inflation in Presence of Scalar Field
Sergei D. Odintsov, Simone D'Onofrio, Tanmoy Paul
In spirit of the recently proposed four-parameter generalized entropy of apparent horizon, we investigate inflationary cosmology where the matter field inside of the horizon is dom…
Holographic description of gravity coupled with Axion Dark Matter
Simone D'Onofrio
In this work we study the autonomous dynamical system of different models in the formalism of holographic dark energy using the generalized Nojiri-Odintsov cut-off. We expli…
Holographic realization from inflation to reheating in generalized entropic cosmology
Sergei D. Odintsov, Simone D'Onofrio, Tanmoy Paul
The growing cosmological interest of different entropy functions (like the Tsallis entropy, the Rényi entropy, the Barrow entropy, the Sharma-Mittal entropy, the Kaniadakis entropy…
The Reissner-Nordström-Tangherlini solution from scattering amplitudes of charged scalars
Simone D'Onofrio, Federica Fragomeno, Claudio Gambino +1
The metric and the electromagnetic potential generated by a static, spherically symmetric charged massive object in any dimension are given by the Reissner-Nordström-Tangherlini so…
