Abstract
There are indications that many astrophysical black holes may be be rapidly spinning. General relativity predicts that a high-spin black hole has an emergent conformal symmetry near its event horizon. Using this symmetry, we analytically predict the polarized near-horizon emissions for high-spin black holes and find a distinctive pattern of whorls aligned with the spin.
