Physical process first law and caustic avoidance for Rindler horizon

Understand

We study the perturbation induced by a slowly rotating massive object as it passes through a Rindler horizon.

• It is shown that the passage of this object can be approximately modeled as Delta\,function type tidal distortions hitting the horizon.
• Further, following the analysis presented by Amsel, Marolf and Virmani related to the issue of the validity of physical process first law, we establish a condition on the size of the object so that this law holds for the Rindler horizon.
