Thermodynamic formulation of Cotton gravity in the Codazzi parametrization
Shayesteh Ghaffari, Giuseppe Gaetano Luciano, Carlo Alberto Mantica
We develop a thermodynamic formulation of Cotton gravity in the Codazzi parametrization, providing a general framework in which the gravitational dynamics can be interpreted in ter…
Gravitational Collapse of an Inhomogeneous Fluid in Rastall Theory
Akbar Jahan, Naser Sadeghnezhad, Amir Hadi Ziaie
We study spherically symmetric gravitational collapse of an inhomogeneous fluid with anisotropic energy momentum tensor (EMT) in Rastall gravity. Considering a linear equation of s…
Trace anomaly contributions to semi-classical wormhole geometries
Mohammad Reza Mehdizadeh, Amir Hadi Ziaie, Francisco S. N. Lobo
We investigate wormhole solutions within the framework of the semi-classical Einstein equations in the presence of the conformal anomaly (or trace anomaly). These solutions are sou…
Singularity Avoidance in Gravitational Collapse of an Inhomogeneous Fluid in Rastall Gravity
Akbar Jahan, Halime Miraghaei, Shayesteh Ghaffari +1
Various types of inhomogeneous collapse models in general relativity (GR) lead to the formation of spacetime singularities either visible or hidden by a spacetime horizon. Our aim…
Black Hole Thermodynamics in Harada's inspired theory of gravity: Stability, Phase Structure and Geometrothermodynamics
S. Ghaffari, G. G. Luciano
In this paper, we investigate the thermodynamic properties of spherically symmetric, static black hole solutions within the framework of Conformal Killing Gravity (CKG). This is a…
H0 tension in Tsallis and Renyi statistics
Naser Sadeghnezhad
Motivated by recent attempts to study the implications of Tsallis and Renyi statistics in gravitational, cosmological, and astrophysical systems, the possible relationships between…
