Optical Landscapes and High-Energy Collisions in Hairy Horndeski Gravity
Filipe Cattete Alves, Rodrigo Maier
We investigate the null geodesic structure, photon sphere dynamics, and high-energy particle collisions within a class of static, spherically symmetric hairy Horndeski black holes.…
A No-Go Theorem for Topological Bridges with Matter-Vacuum Coupling
Rodrigo Maier
Traversable topological bridges traditionally require exotic matter, violating the Null Energy Condition (NEC). This essay investigates whether matter-vacuum coupling can circumven…
The Vacuum Displacement Principle: Theoretical Framework and Local Phenomenology
Rodrigo Maier
We present a modified gravitational framework in which the standard Einstein field equations are sourced by a classical matter sector coupled to a Higgs-type scalar field model…
General Boosted Black Holes: A First Approximation
Rodrigo Maier
In this paper we obtain an approximate solution of Einstein field equations which describes a general boosted Kerr-Newman black hole relative to a Lorentz frame at future null infi…
Relativistic Einstein Rings of Reissner-Nordström metric Black Holes Nonminimally Coupled to Electrodynamics
Rodrigo Maier
In this paper we examine the relativistic Einstein rings assuming a nonminimal coupling between gravitation and electromagnetism in a Reissner-Norström background. Starting from a…
Boosted Kerr-Newman Black Holes
Rafael F. Aranha, Rodrigo Maier
In this paper we obtain a new solution of Einstein field equations which describes a boosted Kerr-Newman black hole relative to a Lorentz frame at future null infinity. To simplify…
Scalar Perturbations in Nonsingular Universes from Interacting Vacuum
Filipe Cattete Alves, Rodrigo Maier
In this paper we examine the stability of scalar perturbations in nonsingular models which emerge from an interacting vacuum component. The analysis developed in this paper relies…
Charged Black Holes from Interacting Vacuum
Rodrigo Maier, Manuella Corrêa e Silva
In this paper charged black holes are obtained assuming that a Born-Infeld electrodynamics may arise from an interaction between the electromagnetic field and a vacuum component. I…
Particle Dynamics on Test Papapetrou Fields of Vacuum Spacetimes
Rodrigo Maier
In this paper we examine the dynamics of particles subjected to test Papapetrou fields of vacuum spacetimes. The staring point of our analysis is based on fundamental electrodynami…
