Black Hole Absorption Rates from Conservation Laws
Burkhard Schwab
Harvard
Abstract:
Conservation of energy and the ``large gauge symmetries'' of electromagnetism fully constrain the absorption rate of low-energy electromagnetic radiation by black holes. I will show this explicitly for non-evaporating, spherically symmetric black holes in arbitrary space-time dimensions larger than 3. I'll also discuss some interesting extensions of the program. Based on arXiv:1609.04397.
