Radiation interference from sources rotating around Schwarzschild black holes

TL;DR

This paper studies how the curvature of spacetime around a Schwarzschild black hole affects the interference patterns of radiation emitted by multiple sources in circular motion, especially as the number of sources increases.

Contribution

It introduces an analysis of interference effects of scalar radiation sources around black holes, highlighting the transition from radiating to non-radiating regimes with more sources.

Findings

Interference patterns are significantly influenced by spacetime curvature.

A transition from radiating to non-radiating regimes occurs as the number of sources increases.

The study provides insights into radiation behavior near black holes.

Abstract

We investigate the influence of the spacetime curvature on the interference of the radiation emitted by an ensemble of scalar sources in circular motion around a Schwarzschild black hole. We pay particular attention to the transition from the radiating to the non-radiating regime as the number of sources increases.
