Josephson's effect in the Schwarzschild background

Reggie C. Pantig, Ali Övgün

We develop a fully covariant, analytic framework for Josephson phenomena in static curved spacetimes and specialize it to the Schwarzschild exterior. The formulation rests on two i…

Time-dependent black hole lensing from ringdown quasinormal mode

Reggie C. Pantig

Is it possible to find imprints of a black hole ringdown through gravitational lensing? To address this question, we formulate an analytic description of weak-field and strong-defl…

Shadow Ringing of Black Holes from Photon Sphere Quasinormal Modes

Reggie C. Pantig

The recent convergence of gravitational-wave (GW) observations and black hole imaging provides complementary probes of strong-gravity dynamics. While the black hole shadow is typic…

Gravitational Black Hole Shadow Spectroscopy

Reggie C. Pantig, Ali Övgün

In this work, we develop a generalized perturbative framework for gravitational shadows in static, spherically symmetric spacetimes. Building upon the recent two-parameter perturba…
