It is natural to ask whether gravitational waves might have effects on matter or light closer to the sources, where the waves are stronger, but with the effects being observable on the Earth. In particular, one might search for modulations in light c ...

An introduction to the mechanics of black holes
... In section 2, we introduce the notion of Killing horizon. This concept is adapted for black holes in equilibrium in stationary spacetimes. We will show how the zero law of mechanics, the consistency of a specific quantity defined on the horizon, directly comes out of the definitions. The tools neces ...
