Accretion dynamics of thin and thick disks in charged Kalb-Ramond black holes
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +5
In this work, we investigate the accretion properties of an electrically charged, static, spherically symmetric black hole in Kalb-Ramond (KR) gravity, where a dimensionless parame…
Black bounce sourced by non-minimally coupled linear electrodynamics and a canonical scalar field through a thin shell at the throat
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +5
We construct a novel class of black bounce solutions within General Relativity, sourced by a canonical scalar field non-minimally coupled to linear electrodynamics, establishing a…
Scalar-Electromagnetic Couplings as Source of Deformed Black Hole: From Shadows to Thermodynamic Topology
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +5
We reconstruct a static and spherically symmetric black hole geometry originally proposed as an effective metric by identifying a consistent matter source derived from a fundamenta…
Free-falling test particles in a charged Kalb-Ramond black hole: gravitational Doppler effect and tidal forces
Daniela S. J. Cordeiro, Ednaldo L. B. Junior, José Tarciso S. S. Junior +5
Space-times exhibiting spontaneous Lorentz symmetry-breaking have recently attracted much attention, with Kalb-Ramond (KR) gravity providing a notable example. In this context, we…
Dyonic regular black bounce solutions in General Relativity
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +3
This work explores dyonic black bounce (BB) solutions within the framework of General Relativity (GR), coupled with nonlinear electrodynamics (NLED) and scalar fields (SFs). Previo…

This paper presents a systematic exploration of exact solutions for electrically charged wormholes, black holes, and black bounces within the hybrid metric-Palatini gravity (HMPG)…
Charged black hole solutions in gravity coupled to nonlinear electrodynamics
Gabriel I. Róis, José Tarciso S. S. Junior, Francisco S. N. Lobo +2
In this work, we investigate static and spherically symmetric black hole solutions in gravity, where is the curvature scalar and is the trace of the energy-momentu…
Constraints on the -parameter for the vacuum solution of Cotton gravity with geodesics and shadows
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +4
We consider a recently introduced extension of General Relativity dubbed as Cotton gravity (CG), based on the use of the Cotton tensor, to estimate the size of a new constant a…
Black holes and regular black holes in coincident gravity coupled to nonlinear electrodynamics
José Tarciso S. S. Junior, Francisco S. N. Lobo, Manuel E. Rodrigues
In this work, we consider an extension of the symmetric teleparallel equivalent of General Relativity (STEGR), namely, gravity, by including a boundary term $\mathb…
Observations on the massive particle surface method
Ednaldo L. B. Junior, José Tarciso S. S. Junior, Francisco S. N. Lobo +3
The geodesic method has played a crucial role in understanding the circular orbits generated by compact objects, culminating in the definition of the photon sphere, which was later…

José Tarciso S. S. Junior, Francisco S. N. Lobo, Manuel E. Rodrigues
In this work, we explore black hole and regular black hole solutions in the recently proposed Conformal Killing Gravity (CKG). This theory is of third order in the derivatives of t…
