Braking--Radiation: An Energy Source for a Relativistic Fireball

TL;DR

The paper shows that a moving black hole suddenly stopping emits a spherical shell of radiation with energy equal to its initial kinetic energy, observable as a relativistic fireball.

Contribution

It introduces a novel mechanism where a moving black hole's sudden halt produces a spherical relativistic fireball with energy matching its initial kinetic energy.

Findings

A moving black hole's sudden stop results in a spherical radiative shell.

The emitted energy equals the black hole's initial kinetic energy.

This process creates a relativistic fireball observable from afar.

Abstract

If the Schwarzschild black-hole is moving rectilinearly with uniform 3-velocity and suddenly stops, according to a distant observer, then we demonstrate that this observer will see a spherical light--like shell or "relativistic fireball" radiate outwards with energy equal to the original kinetic energy of the black-hole.
