This review is concerned with the motion of a point scalar charge, a point electric charge,
and a point mass in a specified background spacetime. In each of the three cases the …

This review is concerned with the gravitational self-force acting on a mass particle in orbit
around a large black hole. Renewed interest in this old problem is driven by the prospects of …

Searches for gravitational waves from compact binaries focus mostly on quasicircular motion
with the rationale that wave emission circularizes the orbit. Here, we study the generality of …

Ultralight scalars have been predicted in a variety of scenarios and advocated as a possible
component of dark matter. These fields can form compact regular structures known as boson …

A bstract Inspired by real-time computations in AdS black holes, we propose a method to
obtain the influence phase of a cosmological observer by calculating the on-shell action on …

We study gravitational wave memory effect in the Friedmann-Robertson-Walker
cosmological model with matter and a cosmological constant. Since the background is …

We investigate the space-time dependence of electromagnetic fields produced by charged
participants in an expanding fluid. To address this problem, we need to solve the Maxwell's …

The “memory effect” is the permanent change in the relative separation of test particles
resulting from the passage of gravitational radiation. We investigate the memory effect for a …

A key source for LISA will be the inspiral of compact objects into massive black holes.
Recently Mino has shown that in the adiabatic limit, gravitational waveforms for these …

We explicitly calculate the gravitational wave memory effect for classical point particle
sources in linearized gravity off an even dimensional Minkowski background. We show that …
