Migrating Carrollian particles on magnetized black hole horizons

Abstrakt

By considering a misaligned (asymptotically uniform) magnetic field in the background of a rotating black hole, we uncover a possibility for a highly nontrivial 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."
