With the arrival of the era of gravitational wave astronomy, the strong gravitational field
regime will be explored soon in various aspects. In this article, we provide a general review …

This chapter is a brief review on the existence and basic properties of static, spherically
symmetric regular black hole solutions of general relativity where the source of gravity is …

In this paper, we investigate the properties of the first excited state Dirac stars (DSs) with
higher azimuthal harmonic index (specifically, the azimuthal harmonic indexes m D= 3/2 …

We consider spherically symmetric configurations in general relativity (GR), supported by
nonlinear electromagnetic fields with gauge-invariant Lagrangians depending on the single …

We consider rational nonlinear electrodynamics with the Lagrangian ℒ=− ℱ/(1+ 2 β
ℱ)(ℱ=(1/4) F μ ν F μ ν is the Lorentz invariant), proposed in Ref. 63, coupled to General …

It is shown that the existence of static, cylindrically symmetric wormholes does not require
violation of the weak or null energy conditions near the throat, and cylindrically symmetric …

We obtain an exact spherically symmetric and magnetically charged black hole solution in
4D Einstein− Gauss− Bonnet gravity coupled with nonlinear electrodynamics with the …

We study the Dirac equation minimally coupled to general relativity using quantum field
theory and the semiclassical gravity approximation. Previous studies of the Einstein-Dirac …

We consider configurations consisting of a gravitating nonlinear spinor field ψ, with a
nonlinearity of the type λ (ψ¯ ψ) 2, minimally coupled to Maxwell and Proca fields through …

We study configurations consisting of a gravitating spinor field ψ with a nonlinearity of the
type λ (ψ¯ ψ) 2. To ensure spherical symmetry of the configurations, we use two spin-1 2 …
