Gravitational Atoms from Topological Stars
Ibrahima Bah, Emanuele Berti, Bogdan Ganchev +2
We study the bound states of a massive scalar field around a topological star, and show that these are strictly normal modes. This yields a genuine gravitational atom, sharply dist…
Perturbations of Plane Waves and Quadratic Quasinormal Modes on the Lightring
Kwinten Fransen, David Pereñiguez, Jaime Redondo-Yuste
We study second order gravitational perturbations on plane wave spacetimes from both the metric and curvature perturbation points of view. For the former, we explicitly use the iso…
On the non-zero Love numbers of magnetic black holes
David Pereñiguez, Edgars Karnickis
Black holes are believed to possess vanishing Love numbers, which implies that they do not deform in the presence of external tides. This fact has been verified in a number of scen…
Ringdown nonlinearities in the eikonal regime
Bruno Bucciotti, Vitor Cardoso, Adrien Kuntz +2
The eikonal limit of black hole quasinormal modes (the large multipole limit ) can be realized geometrically as a next-to-leading order solution to the geometric optics…
