The excitation of the axial quasi-normal modes of a relativistic star by scattered particles is studied by evolving the time dependent perturbation equations. This work is the first step towards the understanding of more complicated perturbative processes, like the capture or the scattering of particles by rotating stars. In addition, it may serve as a test for the results of the full nonlinear evolution of binary systems.

  1. Optimal frequency scales for probing black-hole geometries

    gr-qc 2026-08 conditional novelty 6.0 of 10

    A Gaussian pulse extracts the most black-hole metric information when its width is about the inverse square root of the effective-potential maximum, not when it is as narrow as possible.

  2. Matter environments around black holes: geodesics, light rings, and ultracompact configurations

    gr-qc 2025-12 conditional novelty 5.0 of 10

    Dark-matter halos modeled as Einstein clusters generically move the ISCO inward and the light ring outward, and ultracompact halos can add extra light rings, trapped modes, and secondary horizons.

  3. Tests of General Relativity with Binary Black Holes from the second LIGO-Virgo Gravitational-Wave Transient Catalog

    gr-qc 2020-10 accept novelty 5.0 of 10

    No evidence for deviations from general relativity is found in LIGO-Virgo binary black hole events, with improved constraints on waveform parameters, graviton mass, and ringdown properties.
