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.…

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 mode…

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…

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…

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…

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…
