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…
