Frames and Slicings for Angular Momentum in Post-Minkowski Scattering
Samuel E. Gralla, Kunal Lobo, Hongji Wei
In relativistic physics, angular momentum is paired with a lesser known conserved quantity, the "mass moment", which appears as the time-space components of the angular momentum te…

Electromagnetic Scoot
Samuel E. Gralla, Kunal Lobo
Recent work on scattering of massive bodies in general relativity has revealed that the mechanical center of mass of the system (or, more precisely, its relativistic mass moment) u…

Self-force effects in post-Minkowskian scattering
Samuel E. Gralla, Kunal Lobo
We revisit the old problem of the self-force on a particle moving in a weak-field spacetime in the context of renewed interest in two-body gravitational scattering. We analytically…
