# Migrating Carrollian particles on magnetized black hole horizons

## TL;DR

This paper explores the complex, time-dependent motion of Carrollian particles on rotating black hole horizons influenced by misaligned magnetic fields, revealing oscillatory behaviors akin to butterfly migration.

## Contribution

It introduces a novel analysis of Carrollian particle dynamics on black hole horizons under magnetic perturbations, highlighting non-trivial, oscillatory motion patterns.

## Key findings

- Carrollian particles exhibit latitudinal oscillations on black hole horizons.
- Magnetic field misalignment induces complex, time-dependent velocities.
- The particle motion resembles butterfly migration patterns.

## Abstract

By considering a misaligned (asymptotically uniform) magnetic field in the background of a rotating black hole, we uncover a possibility for a highly non-trivial motion of Carrollian particles on the black hole horizon that is characterized by a time-dependent velocity field and reminds us (because of its latitudinal oscillations) of a 'monarch butterfly migration'.
