Classical Double Copy: Horizons, Quasinormal Modes, and Penrose Limits

ORAL  · Invited

Abstract

First, we will review the classical double copy, which maps exact solutions of classical gauge theories like electromagnetism, to solutions of general relativity. We will discuss why a position-space map is feasible, and then relate several gravitational objects (including horizons, quasinormal modes, and Penrose limits) to their gauge theory analogues.
