A bstract The double copy relates scattering amplitudes in gauge and gravity theories, and
has also been extended to classical solutions. In this paper, we study solutions in three …

In this paper, we study the deflection of light by a class of phantom black hole and wormhole
solutions in the weak limit approximation. More specifically, in the first part of this work we …

We have studied the shadow and its luminosity for a static and regular phantom compact
object under the static spherical accretion and the infalling spherical accretion, respectively …

Motivated by a new model of nonlinear electrodynamics known as Modified Maxwell
(ModMax) theory, an exact analytical solution for black holes is obtained by coupling …

We explore a formulation of the thermodynamic geometry of black holes and prove that the
divergent points of the specific heat correspond exactly to the singularities of the …

We study the thermodynamic phase transition of a quantum-corrected Schwarzschild black
hole. The modified metric affects the critical temperature which is slightly less than the …

Motivated by high interest in Lorentz invariant massive gravity models known as dRGT
massive gravity, we present an exact phantom black hole solution in this theory of gravity …

In this letter, we first redefine our formalism of the thermodynamic geometry introduced in
[1],[2] by changing coordinates of the thermodynamic space by means of Jacobian matrices …

The early literature on black hole thermodynamics ignored the PV term associated with the
existence of a fundamental physical constant in the black hole solution. The inclusion of this …

In this paper, we obtain exact phantom (A) dS black hole solutions in the context of F (R)
gravity with topological spacetime in four dimensions. Then, we study the effects of different …
