Strings near black holes are Carrollian
We demonstrate that strings near the horizon of a Schwarzschild black hole, when viewed
by a stationary observer at infinity, probe a string Carroll geometry, where the effective light …

Strings near black holes are Carrollian. Part II
A bstract We study classical closed bosonic strings probing the near-horizon region of a non-
extremal black hole and show that this corresponds to understanding string theory in the …
