Gauge-invariant observables in gravity and electromagnetism: black hole backgrounds and null dressings
We address questions regarding construction and implications of gauge-invariant “dressed” observables in nontrivial background geometries such as that of a black hole. Formally, such observables can be constructed, e.g., by locating points with geodesics launched from infinity. However, practical co...
