# Soft Hair on Black Holes.

@article{Hawking2016SoftHO, title={Soft Hair on Black Holes.}, author={Stephen William Hawking and Malcolm Perry and Andrew Strominger}, journal={Physical review letters}, year={2016}, volume={116 23}, pages={ 231301 } }

It has recently been shown that Bondi-van der Burg-Metzner-Sachs supertranslation symmetries imply an infinite number of conservation laws for all gravitational theories in asymptotically Minkowskian spacetimes. These laws require black holes to carry a large amount of soft (i.e., zero-energy) supertranslation hair. The presence of a Maxwell field similarly implies soft electric hair. This Letter gives an explicit description of soft hair in terms of soft gravitons or photons on the black hole…
