DOI: 10.1016/j.aop.2019.04.008
Abstract: We calculate the effects of the electromagnetic self-force on a charged particle outside a five dimensional Myers-Perry space-time. Based on our earlier work [1], we obtain the self-force using quaternions in Janis-Newman and Giampieri algorithms.… read more here.

DOI: 10.1016/s0034-4877(19)30068-0
Abstract: The self-force of a point charge moving on a rectilinear trajectory is obtained, with no need of any explicit removal of infinities, as the negative of the time rate of change of the momentum of… read more here.

Abstract: Inspirals of stellar-mass objects into massive black holes will be important sources for the space-based gravitational-wave detector LISA. Modelling these systems requires calculating the metric perturbation due to a point particle orbiting a Kerr black… read more here.

Abstract: We semianalytically investigate the scalar self-force experienced in the final stages of extreme mass ratio inspirals of nonspinning scalar particles into supermassive nearly extremal Kerr black holes. We exploit the near-horizon conformal symmetry to find… read more here.

DOI: 10.1103/physrevd.104.084011
Abstract: Extreme-mass-ratio inspirals (EMRIs), compact binaries with small mass-ratios 1, will be important sources for low-frequency gravitational wave detectors. Almost all EMRIs will evolve through important transient orbital rθ-resonances, which will enhance or diminish their gravitational… read more here.
