نویسندگان
چکیده
We study the displacement memory effect and its connection with extended-BMS symmetries near horizon of black holes. show there is a permanent shift in geodesic deviation vector relating two nearby timelike geodesics placed close to holes, upon passage gravitational waves. also relate this asymptotic hole spacetimes. The relative position detectors shown be induced by combination BMS generators horizon. possesses similarities same obtained far region.

Dilaton black holes near the horizon.
Generic U(1) 4-d black holes with unbroken N = 1 supersymmetry are shown to tend to a Robinson-Bertotti type geometry with a linear dilaton and doubling of unbroken supersymmetries near the horizon. Purely magnetic dilatonic black holes, which have unbroken N = 2 supersymmetry, behave near the horizon as a 2-d linear dilaton vacuum ⊗S2. This geometry is invariant under 8 supersymmetries, i.e. h...
متن کاملNear-horizon symmetries of extremal black holes
Recent work has demonstrated an attractor mechanism for extremal rotating black holes subject to the assumption of a near-horizon SO(2, 1) symmetry. We prove the existence of this symmetry for any extremal black hole with the same number of rotational symmetries as known four and five dimensional solutions (including black rings). The result is valid for a general two-derivative theory of gravi...
متن کاملNear-Horizon Conformal Structure of Black Holes
The near-horizon properties of a black hole are studied within an algebraic framework, using a scalar field as a simple probe to analyze the geometry. The operator H governing the near-horizon dynamics of the scalar field contains an inverse square interaction term. It is shown that the operators appearing in the corresponding algebraic description belong to the representation space of the Vira...
متن کاملBTZ black holes and the near-horizon geometry of higher-dimensional black holes
We investigate the connection between the BTZ black holes and the near-horizon geometry of higher-dimensional black holes. Under mild conditions, we show that (i) if a black hole has a global structure of the Reissner-Nordstrom black hole type, its near-horizon geometry is AdS2 times a sphere, and further (ii) if such a black hole is obtained from a boosted black string by dimensional reduction...
متن کاملClassification of Near-Horizon Geometries of Extremal Black Holes
Any spacetime containing a degenerate Killing horizon, such as an extremal black hole, possesses a well-defined notion of a near-horizon geometry. We review such near-horizon geometry solutions in a variety of dimensions and theories in a unified manner. We discuss various general results including horizon topology and near-horizon symmetry enhancement. We also discuss the status of the classif...
