Real-time creation of curved space-time for gravitational lensing in phononic crystals

Metamaterials, 2023
We propose a method to generate an artificial curved space-time metric that mimics the metric at the vicinity of a black hole. This metric supports the gravitational lensing phenomenon, describing the deflection of light beams around the event horizon ...

The influence of uniform magnetic fields on strong field gravitational lensing by Kerr black holes

Journal of Cosmology and Astroparticle Physics
We examine gravitational lensing strong deflection limit (SDL) by magnetized Kerr black holes (MKBHs), which are accurate Kerr-Bertotti-Robinson solutions for Kerr black holes in a uniform magnetic field with additional magnetic field strength B apart ...

Scattering perspective on gravitational lensing

Physical Review D
Gravitational waves propagating across gravitational potentials undergo lensing effects that, in the wave-optics regime, manifest as frequency-dependent amplitude and phase modulations.

Gravitational Waves from Binary Extreme Mass Ratio Inspirals: Doppler Shift and Beaming, Resonant Excitation, Helicity Oscillations, and Self-Lensing.

Physical Review Letters
We study gravitational waves from a stellar-mass binary orbiting a spinning supermassive black hole, a system referred to as a binary extreme mass ratio inspiral (b-EMRI).

Strong gravitational lensing effects of black holes with quantum hair


According to the no-hair theorem, stationary black holes are uniquely characterized by their mass, charge, and angular momentum. In this paper, we explore quantum hair by deriving the quantum-corrected black hole metric within the Barvinsky-Vilkovisky ...
