We develop a long-distance world-volume effective theory that captures the black hole dynamics at scales much larger than the short scale. In this limit the black hole is regarded as a blackfold: a black brane (possibly boosted locally) whose world volume spans a curved submanifold of the spacetime. This approach reveals black objects with novel horizon geometries and topologies more complex than the black ring, but more generally it provides a new organizing framework for the dynamics of higher-dimensional black holes.4 p.application/pdfeng(c) American Physical Society, 2009Forats negres (Astronomia)Black holes (Astronomy)info:eu-repo/semantics/article5765792019-09-06info:eu-repo/semantics/openAccess
