We investigate the possibility of overcharging spherically symmetric black holes in
spacetime dimensions D> 4 by the capture of a charged particle. We generalize Wald's …

In the DGP model, the graviton is unstable, which leads to a modification of gravity at
cosmological distances. In particular, this leads to the leakage of gravitational waves from …

A particle moving with variable acceleration in the flat space-time affects the self-force due to
outgoing radiation. The gravitational fields bring an additional contribution to self-force due …

We explore possible manifestations of an odd number of extra dimensions in gravitational
radiation, which are associated with violation of Huygens' principle in flat odd-dimensional …

Huygens principle violation in a spacetime of odd dimensions leads to the fact that the
retarded massless fields of localised sources depend on their history of motion preceding …

We consider a binary system of spinning compact objects with internal structure, moving
along an exactly circular orbit, and modeled within the multipolar gravitational skeleton …

The self-force problem—which asks how self-interaction affects a body's motion—has been
poorly studied for spacetime dimensions d≠ 4. We remedy this for all d≥ 3 by …

We develop an approach to calculate the self-force on a charged particle held in place in a
curved spacetime, in which the particle is attached to a massless string and the force is …

Motivated by applications to the study of self-force effects in scalar-tensor theories of gravity,
we calculate the self-force exerted on a scalar charge in a circular orbit about a Reissner …

We consider the arbitrarily coupled field and self-force of a static massless scalar charge in
cylindrical spacetimes with one or two asymptotic regions, with the only matter content …
