Cataclysmic astrophysical phenomena can produce impulsive gravitational waves that can possibly be detected by the advanced versions of present-day detectors in the future. The …
We study horizon shells and soldering freedom for extreme black holes and how supertranslation-like Bondi-Metzner-Sachs (BMS) symmetries appear as soldering …
Abstract The extreme Reissner–Nordström (ERN) solution has a discrete conformal isometry that maps the future event horizon to future null infinity and vice versa, the Couch–Torrence …
A bstract We study the displacement memory effect and its connection with the extended- BMS symmetries near the horizon of black holes. We show there is a permanent shift in the …
The memory effect, in the context of gravitational-waves (GWs), manifests itself in the permanent relative displacement of test masses when they encounter the GWs. A number of …

We revisit the symmetries of an isolated horizon (IH), exploiting some freedom in the choice of intrinsic data. The supertranslations are realized as additional symmetries. Furthermore, it …
